HIV (human immunodeficiency virus)-About sexually transmitted diseases

HIV (human immunodeficiency virus)-About sexually transmitted diseases
HIV stands for human immunodeficiency virus. It weakens a person’s immune system by destroying important cells that fight disease and infection. No effective cure exists for HIV. But with proper medical care, HIV can be controlled. Some groups of people in the United States are more likely to get HIV than others because of many factors, including their sex partners, their risk behaviors, and where they live. This section will give you basic information about HIV, such as how it’s transmitted, how you can prevent it, and how to get tested for HIV.

About HIV/AIDS

Image of red blood cellsHIV is a virus spread through body fluids that affects specific cells of the immune system, called CD4 cells, or T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. When this happens, HIV infection leads to AIDS. Learn more about the stages of HIV and how to tell whether you’re infected.

HIV stands for human immunodeficiency virus. It is the virus that can lead to acquired immunodeficiency syndrome, or AIDS. Unlike some other viruses, the human body cannot get rid of HIV. That means that once you have HIV, you have it for life.
No safe and effective cure currently exists, but scientists are working hard to find one, and remain hopeful. Meanwhile, with proper medical care, HIV can be controlled. Treatment for HIV is often called antiretroviral therapy or ART. It can dramatically prolong the lives of many people infected with HIV and lower their chance of infecting others. Before the introduction of ART in the mid-1990s, people with HIV could progress to AIDS in just a few years. Today, someone diagnosed with HIV and treated before the disease is far advanced can have a nearly normal life expectancy.

basics_whereHIV_130x130.jpgScientists identified a type of chimpanzee in West Africa as the source of HIV infection in humans. They believe that the chimpanzee version of the immunodeficiency virus (called simian immunodeficiency virus, or SIV) most likely was transmitted to humans and mutated into HIV when humans hunted these chimpanzees for meat and came into contact with their infected blood. Studies show that HIV may have jumped from apes to humans as far back as the late 1800s. Over decades, the virus slowly spread across Africa and later into other parts of the world. We know that the virus has existed in the United States since at least the mid- to late 1970s.
HIV disease has a well-documented progression. Untreated, HIV is almost universally fatal because it eventually overwhelms the immune system—resulting in acquired immunodeficiency syndrome (AIDS). HIV treatment helps people at all stages of the disease, and treatment can slow or prevent progression from one stage to the next.
A person can transmit HIV to others during any of these stages:
Acute infection: Within 2 to 4 weeks after infection with HIV, you may feel sick with flu-like symptoms. This is called acute retroviral syndrome (ARS) or primary HIV infection, and it’s the body’s natural response to the HIV infection. (Not everyone develops ARS, however—and some people may have no symptoms.)
During this period of infection, large amounts of HIV are being produced in your body. The virus uses important immune system cells called CD4 cells to make copies of itself and destroys these cells in the process. Because of this, the CD4 count can fall quickly.
Your ability to spread HIV is highest during this stage because the amount of virus in the blood is very high.
Eventually, your immune response will begin to bring the amount of virus in your body back down to a stable level. At this point, your CD4 count will then begin to increase, but it may not return to pre-infection levels.
Clinical latency (inactivity or dormancy): This period is sometimes called asymptomatic HIV infection or chronic HIV infection. During this phase, HIV is still active, but reproduces at very low levels. You may not have any symptoms or get sick during this time. People who are on antiretroviral therapy (ART) may live with clinical latency for several decades. For people who are not on ART, this period can last up to a decade, but some may progress through this phase faster. It is important to remember that you are still able to transmit HIV to others during this phase even if you are treated with ART, although ART greatly reduces the risk. Toward the middle and end of this period, your viral load begins to rise and your CD4 cell count begins to drop. As this happens, you may begin to have symptoms of HIV infection as your immune system becomes too weak to protect you .
AIDS (acquired immunodeficiency syndrome): This is the stage of infection that occurs when your immune system is badly damaged and you become vulnerable to infections and infection-related cancers called opportunistic illnesses. When the number of your CD4 cells falls below 200 cells per cubic millimeter of blood (200 cells/mm3), you are considered to have progressed to AIDS. (Normal CD4 counts are between 500 and 1,600 cells/mm3.) You can also be diagnosed with AIDS if you develop one or more opportunistic illnesses, regardless of your CD4 count. Without treatment, people who are diagnosed with AIDS typically survive about 3 years. Once someone has a dangerous opportunistic illness, life expectancy without treatment falls to about 1 year. People with AIDS need medical treatment to prevent death.
The only way to know if you are infected with HIV is to be tested. You cannot rely on symptoms to know whether you have HIV. Many people who are infected with HIV do not have any symptoms at all for 10 years or more. Some people who are infected with HIV report having flu-like symptoms (often described as “the worst flu ever”) 2 to 4 weeks after exposure. Symptoms can include:
  • Fever
  • Enlarged lymph nodes
  • Sore throat
  • Rash
These symptoms can last anywhere from a few days to several weeks. During this time, HIV infection may not show up on an HIV test, but people who have it are highly infectious and can spread the infection to others.
However, you should not assume you have HIV if you have any of these symptoms. Each of these symptoms can be caused by other illnesses. Again, the only way to determine whether you are infected is to be tested for HIV infection. For information on where to find an HIV testing site,
  • Visit National HIV and STD Testing Resources and enter your ZIP code.
  • Text your ZIP code to KNOWIT (566948), and you will receive a text back with a testing site near you.
  • Call 800-CDC-INFO (800-232-4636) to ask for free testing sites in your area.
These resources are confidential. You can also ask your health care provider to give you an HIV test.
Two types of home testing kits are available in most drugstores or pharmacies: one involves pricking your finger for a blood sample, sending the sample to a laboratory, then phoning in for results. The other involves getting a swab of fluid from your mouth, using the kit to test it, and reading the results in 20 minutes. Confidential counseling and referrals for treatment are available with both kinds of home tests.
If you test positive for HIV, you should see your doctor as soon as possible to begin treatment.
For most people, the answer is no. Most reports of a cure involve HIV-infected people who needed treatment for a cancer that would have killed them otherwise. But these treatments are very risky, even life-threatening, and are used only when the HIV-infected people would have died without them. Antiretroviral therapy (ART), however, can dramatically prolong the lives of many people infected with HIV and lower their chance of infecting others. It is important that people get tested for HIV and know that they are infected early so that medical care and treatment have the greatest effect.

Trichomoniasis-About sexually transmitted diseases

Trichomoniasis-About sexually transmitted diseases

What is trichomoniasis?


Trichomoniasis (or “trich”) is a very common sexually transmitted disease (STD) that is caused by infection with a protozoan parasite called Trichomonas vaginalis. Although symptoms of the disease vary, most women and men who have the parasite cannot tell they are infected.

How common is trichomoniasis?

Trichomoniasis is considered the most common curable STD. In the United States, an estimated 3.7 million people have the infection, but only about 30% develop any symptoms of trichomoniasis. Infection is more common in women than in men, and older women are more likely than younger women to have been infected.

How do people get trichomoniasis?

The parasite is passed from an infected person to an uninfected person during sex. In women, the most commonly infected part of the body is the lower genital tract (vulva, vagina, or urethra), and in men, the most commonly infected body part is the inside of the penis (urethra). During sex, the parasite is usually transmitted from a penis to a vagina, or from a vagina to a penis, but it can also be passed from a vagina to another vagina. It is not common for the parasite to infect other body parts, like the hands, mouth, or anus. It is unclear why some people with the infection get symptoms while others do not, but it probably depends on factors like the person’s age and overall health. Infected people without symptoms can still pass the infection on to others.

What are the signs and symptoms of trichomoniasis?

About 70% of infected people do not have any signs or symptoms. When trichomoniasis does cause symptoms, they can range from mild irritation to severe inflammation. Some people with symptoms get them within 5 to 28 days after being infected, but others do not develop symptoms until much later. Symptoms can come and go.
Men with trichomoniasis may feel itching or irritation inside the penis, burning after urination or ejaculation, or some discharge from the penis.
Women with trichomoniasis may notice itching, burning, redness or soreness of the genitals, discomfort with urination, or a thin discharge with an unusual smell that can be clear, white, yellowish, or greenish.
Having trichomoniasis can make it feel unpleasant to have sex. Without treatment, the infection can last for months or even years.

What are the complications of trichomoniasis?

Trichomoniasis can increase the risk of getting or spreading other sexually transmitted infections. For example, trichomoniasis can cause genital inflammation that makes it easier to get infected with the HIV virus, or to pass the HIV virus on to a sex partner.

How does trichomoniasis affect a pregnant woman and her baby?

Pregnant women with trichomoniasis are more likely to have their babies too early (preterm delivery). Also, babies born to infected mothers are more likely to have an officially low birth weight (less than 5.5 pounds).

How is trichomoniasis diagnosed?

It is not possible to diagnose trichomoniasis based on symptoms alone. For both men and women, your primary care doctor or another trusted health care provider must do a check and a laboratory test to diagnose trichomoniasis.

What is the treatment for trichomoniasis?

Trichomoniasis can be cured with a single dose of prescription antibiotic medication (either metronidazole or tinidazole), pills which can be taken by mouth. It is okay for pregnant women to take this medication. Some people who drink alcohol within 24 hours after taking this kind of antibiotic can have uncomfortable side effects.
People who have been treated for trichomoniasis can get it again. About 1 in 5 people get infected again within 3 months after treatment. To avoid getting reinfected, make sure that all of your sex partners get treated too, and wait to have sex again until all of your symptoms go away (about a week). Get checked again if your symptoms come back.

How can trichomoniasis be prevented?

Using latex condoms correctly every time you have sex will help reduce the risk of getting or spreading trichomoniasis. However, condoms don’t cover everything, and it is possible to get or spread this infection even when using a condom.
The only sure way to prevent sexually transmitted infections is to avoid having sex entirely. Another approach is to talk about these kinds of infections before you have sex with a new partner, so that you can make informed choices about the level of risk you are comfortable taking with your sex life.
If you or someone you know has questions about trichomoniasis or any other STD, especially with symptoms like unusual discharge, burning during urination, or a sore in the genital area, check in with a health care provider and get some answers.

Syphilis-About sexually transmitted diseases

Syphilis-About sexually transmitted diseases

What is syphilis?


Syphilis is an STD that can cause long-term complications if not treated correctly. Symptoms in adults are divided into stages. These stages are primary, secondary, latent, and late syphilis.

How is syphilis spread?

You can get syphilis by direct contact with a syphilis sore during vaginal, anal, or oral sex. Sores can be found on the penis, vagina, anus, in the rectum, or on the lips and in the mouth. Syphilis can also be spread from an infected mother to her unborn baby.

What does syphilis look like?

Syphilis has been called ‘the great imitator’ because it has so many possible symptoms, many of which look like symptoms from other diseases. The painless syphilis sore that you would get after you are first infected can be confused for an ingrown hair, zipper cut, or other seemingly harmless bump. The non-itchy body rash that develops during the second stage of syphilis can show up on the palms of your hands and soles of your feet, all over your body, or in just a few places. Syphilis can also affect the eye and can lead to permanent blindness. This is called ocular syphilis. You could also be infected with syphilis and have very mild symptoms or none at all.
Example of a primary syphilis sore.
Example of a primary syphilis sore.

How can I reduce my risk of getting syphilis?

The only way to avoid STDs is to not have vaginal, anal, or oral sex.
If you are sexually active, you can do the following things to lower your chances of getting syphilis:
  • Being in a long-term mutually monogamous relationship with a partner who has been tested and has negative STD test results;
  • Using latex condoms the right way every time you have sex. Condoms prevent transmission of syphilis by preventing contact with a sore. Sometimes sores occur in areas not covered by a condom. Contact with these sores can still transmit syphilis.

Am I at risk for syphilis?

Any sexually active person can get syphilis through unprotected vaginal, anal, or oral sex. Have an honest and open talk with your health care provider and ask whether you should be tested for syphilis or other STDs. You should get tested regularly for syphilis if you are pregnant, are a man who has sex with men, have HIV infection, and/or have partner(s) who have tested positive for syphilis.

I’m pregnant. How does syphilis affect my baby?

If you are pregnant and have syphilis, you can give the infection to your unborn baby. Having syphilis can lead to a low birth weight baby. It can also make it more likely you will deliver your baby too early or stillborn (a baby born dead). To protect your baby, you should be tested for syphilis during your pregnancy and at delivery and receive immediate treatment if you test positive.
An infected baby may be born without signs or symptoms of disease. However, if not treated immediately, the baby may develop serious problems within a few weeks. Untreated babies can have health problems such as cataracts, deafness, or seizures, and can die.

How do I know if I have syphilis?

Symptoms of syphilis in adults can be divided into stages:

Primary Stage

During the first (primary) stage of syphilis, you may notice a single sore, but there may be multiple sores. The sore is the location where syphilis entered your body. The sore is usually firm, round, and painless. Because the sore is painless, it can easily go unnoticed. The sore lasts 3 to 6 weeks and heals regardless of whether or not you receive treatment. Even though the sore goes away, you must still receive treatment so your infection does not move to the secondary stage.

Secondary Stage

During the secondary stage, you may have skin rashes and/or sores in your mouth, vagina, or anus (also called mucous membrane lesions). This stage usually starts with a rash on one or more areas of your body. The rash can show up when your primary sore is healing or several weeks after the sore has healed. The rash can look like rough, red, or reddish brown spots on the palms of your hands and/or the bottoms of your feet. The rash usually won’t itch and it is sometimes so faint that you won’t notice it. Other symptoms you may have can include fever, swollen lymph glands, sore throat, patchy hair loss, headaches, weight loss, muscle aches, and fatigue (feeling very tired). The symptoms from this stage will go away whether or not you receive treatment. Without the right treatment, your infection will move to the latent and possibly late stages of syphilis.

Latent and Late Stages

The latent stage of syphilis begins when all of the symptoms you had earlier disappear. If you do not receive treatment, you can continue to have syphilis in your body for years without any signs or symptoms. Most people with untreated syphilis do not develop late stage syphilis. However, when it does happen it is very serious and would occur 10–30 years after your infection began. Symptoms of the late stage of syphilis include difficulty coordinating your muscle movements, paralysis (not able to move certain parts of your body), numbness, blindness, and dementia (mental disorder). In the late stages of syphilis, the disease damages your internal organs and can result in death.
A syphilis infection is called an ‘early’ case if a patient has been infected for a year or less, such as during the primary or secondary stages of syphilis. People who have ‘early’ syphilis infections can more easily spread the infection to their sex partners. The majority of early syphilis cases are currently found among men who have sex with men, but women and unborn children are also at risk of infection.

How will my doctor know if I have syphilis?

Most of the time, a blood test can be used to test for syphilis. Some health care providers will diagnose syphilis by testing fluid from a syphilis sore.

Can syphilis be cured?

Darkfield micrograph of Treponema pallidum.
Yes, syphilis can be cured with the right antibiotics from your health care provider. However, treatment will not undo any damage that the infection has already done.

I’ve been treated. Can I get syphilis again?

Having syphilis once does not protect you from getting it again. Even after you’ve been successfully treated, you can still be re-infected. Only laboratory tests can confirm whether you have syphilis. Follow-up testing by your health care provider is recommended to make sure that your treatment was successful.
Because syphilis sores can be hidden in the vagina, anus, under the foreskin of the penis, or in the mouth, it may not be obvious that a sex partner has syphilis. Unless you know that your sex partner(s) has been tested and treated, you may be at risk of getting syphilis again from an untreated sex partner.

Gonorrhea-About sexually transmitted diseases

Gonorrhea-About sexually transmitted diseases

What is gonorrhea?


Gonorrhea is a sexually transmitted disease (STD) that can infect both men and women. It can cause infections in the genitals, rectum, and throat. It is a very common infection, especially among young people ages 15-24 years.

How is gonorrhea spread?

You can get gonorrhea by having vaginal, anal, or oral sex with someone who has gonorrhea. A pregnant woman with gonorrhea can give the infection to her baby during childbirth.

How can I reduce my risk of getting gonorrhea?

The only way to avoid STDs is to not have vaginal, anal, or oral sex.
If you are sexually active, you can do the following things to lower your chances of getting gonorrhea:
  • Being in a long-term mutually monogamous relationship with a partner who has been tested and has negative STD test results;
  • Using latex condoms the right way every time you have sex.

Am I at risk for gonorrhea?

Any sexually active person can get gonorrhea through unprotected vaginal, anal, or oral sex.
If you are sexually active, have an honest and open talk with your health care provider and ask whether you should be tested for gonorrhea or other STDs. If you are a sexually active man who is gay, bisexual, or who has sex with men, you should be tested for gonorrhea every year. If you are a sexually active women younger than 25 years or an older women with risk factors such as new or multiple sex partners, or a sex partner who has a sexually transmitted infection, you should be tested for gonorrhea every year.

I'm pregnant. How does gonorrhea affect my baby?

If you are pregnant and have gonorrhea, you can give the infection to your baby during delivery. This can cause serious health problems for your baby. If you are pregnant, it is important that you talk to your health care provider so that you get the correct examination, testing, and treatment, as necessary. Treating gonorrhea as soon as possible will make health complications for your baby less likely.

How do I know if I have gonorrhea?

Some men with gonorrhea may have no symptoms at all. However, men who do have symptoms, may have:
  • A burning sensation when urinating;
  • A white, yellow, or green discharge from the penis;
  • Painful or swollen testicles (although this is less common).
Most women with gonorrhea do not have any symptoms. Even when a woman has symptoms, they are often mild and can be mistaken for a bladder or vaginal infection. Women with gonorrhea are at risk of developing serious complications from the infection, even if they don’t have any symptoms.
Symptoms in women can include:
  • Painful or burning sensation when urinating;
  • Increased vaginal discharge;
  • Vaginal bleeding between periods.
Rectal infections may either cause no symptoms or cause symptoms in both men and women that may include:
  • Discharge;
  • Anal itching;
  • Soreness;
  • Bleeding;
  • Painful bowel movements.
You should be examined by your doctor if you notice any of these symptoms or if your partner has an STD or symptoms of an STD, such as an unusual sore, a smelly discharge, burning when urinating, or bleeding between periods.

How will my doctor know if I have gonorrhea?

Most of the time, urine can be used to test for gonorrhea. However, if you have had oral and/or anal sex, swabs may be used to collect samples from your throat and/or rectum. In some cases, a swab may be used to collect a sample from a man’s urethra (urine canal) or a woman’s cervix (opening to the womb).
bacteriaAntibiotic-Resistant Gonorrhea

Can gonorrhea be cured?

Yes, gonorrhea can be cured with the right treatment. It is important that you take all of the medication your doctor prescribes to cure your infection. Medication for gonorrhea should not be shared with anyone. Although medication will stop the infection, it will not undo any permanent damage caused by the disease.
It is becoming harder to treat some gonorrhea, as drug-resistant strains of gonorrhea are increasing. If your symptoms continue for more than a few days after receiving treatment, you should return to a health care provider to be checked again.

I was treated for gonorrhea. When can I have sex again?

You should wait seven days after finishing all medications before having sex. To avoid getting infected with gonorrhea again or spreading gonorrhea to your partner(s), you and your sex partner(s) should avoid having sex until you have each completed treatment. If you’ve had gonorrhea and took medicine in the past, you can still get infected again if you have unprotected sex with a person who has gonorrhea.
Photo of woman in pain.Pelvic Inflammatory Disease (PID)

What happens if I don’t get treated?

Untreated gonorrhea can cause serious and permanent health problems in both women and men.
In women, untreated gonorrhea can cause pelvic inflammatory disease (PID). Some of the complications of PID are
  • Formation of scar tissue that blocks fallopian tubes;
  • Ectopic pregnancy (pregnancy outside the womb);
  • Infertilit (inability to get pregnant);
  • Long-term pelvic/abdominal pain.
In men, gonorrhea can cause a painful condition in the tubes attached to the testicles. In rare cases, this may cause a man to be sterile, or prevent him from being able to father a child.
Rarely, untreated gonorrhea can also spread to your blood or joints. This condition can be life-threatening.
Untreated gonorrhea may also increase your chances of getting or giving HIV – the virus that causes AIDS.

human papillomavirus (Genital HPV) Infection - About sexually transmitted diseases

human papillomavirus (Genital HPV) Infection - About sexually transmitted diseases

What is HPV?

HPV is the most common sexually transmitted infection (STI). HPV is a different virus than HIV and HSV (herpes). HPV is so common that nearly all sexually active men and women get it at some point in their lives. There are many different types of HPV. Some types can cause health problems including genital warts and cancers. But there are vaccines that can stop these health problems from happening.

How is HPV spread?

You can get HPV by having vaginal, anal, or oral sex with someone who has the virus. It is most commonly spread during vaginal or anal sex. HPV can be passed even when an infected person has no signs or symptoms.
Anyone who is sexually active can get HPV, even if you have had sex with only one person. You also can develop symptoms years after you have sex with someone who is infected making it hard to know when you first became infected.

Does HPV cause health problems?

In most cases, HPV goes away on its own and does not cause any health problems. But when HPV does not go away, it can cause health problems like genital warts and cancer.
Genital warts usually appear as a small bump or group of bumps in the genital area. They can be small or large, raised or flat, or shaped like a cauliflower. A healthcare provider can usually diagnose warts by looking at the genital area.

Does HPV cause cancer?

HPV can cause cervical and other cancers including cancer of the vulva, vagina, penis, or anus. It can also cause cancer in the back of the throat, including the base of the tongue and tonsils (called oropharyngeal cancer).
Cancer often takes years, even decades, to develop after a person gets HPV. The types of HPV that can cause genital warts are not the same as the types of HPV that can cause cancers.
There is no way to know which people who have HPV will develop cancer or other health problems. People with weak immune systems (including individuals with HIV/AIDS) may be less able to fight off HPV and more likely to develop health problems from it.

How can I avoid HPV and the health problems it can cause?

You can do several things to lower your chances of getting HPV.
Get vaccinated. HPV vaccines are safe and effective. They can protect males and females against diseases (including cancers) caused by HPV when given in the recommended age groups (see “Who should get vaccinated?” below). HPV vaccines are given in three shots over six months; it is important to get all three doses.
Get screened for cervical cancer. Routine screening for women aged 21 to 65 years old can prevent cervical cancer.
If you are sexually active
  • Use latex condoms the right way every time you have sex. This can lower your chances of getting HPV. But HPV can infect areas that are not covered by a condom - so condoms may not give full protection against getting HPV;
  • Be in a mutually monogamous relationship – or have sex only with someone who only has sex with you.

Who should get vaccinated?

All boys and girls ages 11 or 12 years should get vaccinated.
Catch-up vaccines are recommended for males through age 21 and for females through age 26, if they did not get vaccinated when they were younger.
The vaccine is also recommended for gay and bisexual men (or any man who has sex with a man) through age 26. It is also recommended for men and women with compromised immune systems (including people living with HIV/AIDS) through age 26, if they did not get fully vaccinated when they were younger.

How do I know if I have HPV?

There is no test to find out a person’s “HPV status.” Also, there is no approved HPV test to find HPV in the mouth or throat.
There are HPV tests that can be used to screen for cervical cancer. These tests are recommended for screening only in women aged 30 years and older. They are not recommended to screen men, adolescents, or women under the age of 30 years.
Most people with HPV do not know they are infected and never develop symptoms or health problems from it. Some people find out they have HPV when they get genital warts. Women may find out they have HPV when they get an abnormal Pap test result (during cervical cancer screening). Others may only find out once they’ve developed more serious problems from HPV, such as cancers.

How common is HPV and the health problems caused by HPV?

HPV (the virus): About 79 million Americans are currently infected with HPV. About 14 million people become newly infected each year. HPV is so common that most sexually-active men and women will get at least one type of HPV at some point in their lives.
Health problems related to HPV include genital warts and cervical cancer.
Genital warts: About 360,000 people in the United States get genital warts each year.
Cervical cancer: More than 11,000 women in the United States get cervical cancer each year.
There are other conditions and cancers caused by HPV that occur in persons living in the United States.

I'm pregnant. Will having HPV affect my pregnancy?

If you are pregnant and have HPV, you can get genital warts or develop abnormal cell changes on your cervix. Abnormal cell changes can be found with routine cervical cancer screening. You should get routine cervical cancer screening even when you are pregnant.

Can I be treated for HPV or health problems caused by HPV?

There is no treatment for the virus itself. However, there are treatments for the health problems that HPV can cause:
  1. Genital warts can be treated by you or your physician. If left untreated, genital warts may go away, stay the same, or grow in size or number.
  2. Cervical precancer can be treated. Women who get routine Pap tests and follow up as needed can identify problems before cancer develops. Prevention is always better than treatment. For more information visit www.cancer.org.
  3. Other HPV-related cancers are also more treatable when diagnosed and treated early. For more information visit www.cancer.org.

Chlamydia - About sexually transmitted diseases

Chlamydia - About sexually transmitted diseases

What is chlamydia?

Chlamydia is a common STD that can infect both men and women. It can cause serious, permanent damage to a woman's reproductive system, making it difficult or impossible for her to get pregnant later on. Chlamydia can also cause a potentially fatal ectopic pregnancy (pregnancy that occurs outside the womb).

How is chlamydia spread?

You can get chlamydia by having vaginal, anal, or oral sex with someone who has chlamydia.
If your sex partner is male you can still get chlamydia even if he does not ejaculate (cum).
If you’ve had chlamydia and were treated in the past, you can still get infected again if you have unprotected sex with someone who has chlamydia.
If you are pregnant, you can give chlamydia to your baby during childbirth.

How can I reduce my risk of getting chlamydia?

The only way to avoid STDs is to not have vaginal, anal, or oral sex.
If you are sexually active, you can do the following things to lower your chances of getting chlamydia:
  • Being in a long-term mutually monogamous relationship with a partner who has been tested and has negative STD test results;
  • Using latex condoms the right way every time you have sex.

Am I at risk for chlamydia?

Anyone who has sex can get chlamydia through unprotected vaginal, anal, or oral sex. However, sexually active young people are at a higher risk of getting chlamydia. This is due to behaviors and biological factors common among young people. Gay, bisexual, and other men who have sex with men are also at risk since chlamydia can be spread through oral and anal sex.
Have an honest and open talk with your health care provider and ask whether you should be tested for chlamydia or other STDs. If you are a sexually active woman younger than 25 years, or an older woman with risk factors such as new or multiple sex partners, or a sex partner who has a sexually transmitted infection, you should get a test for chlamydia every year. Gay, bisexual, and men who have sex with men; as well as pregnant women should also be tested for chlamydia.
STDs and PregnancySTDs & Pregnancy

I'm pregnant. How does chlamydia affect my baby?

If you are pregnant and have chlamydia, you can pass the infection to your baby during delivery. This could cause an eye infection or pneumonia in your newborn. Having chlamydia may also make it more likely to deliver your baby too early.
If you are pregnant, you should be tested for chlamydia at your first prenatal visit. Testing and treatment are the best ways to prevent health problems.

How do I know if I have chlamydia?

illustration of female anatomy showing fallopian tubes, ovary, cervix, uterus, and vaginaMost people who have chlamydia have no symptoms. If you do have symptoms, they may not appear until several weeks after you have sex with an infected partner. Even when chlamydia causes no symptoms, it can damage your reproductive system.
Women with symptoms may notice
  • An abnormal vaginal discharge;
  • A burning sensation when urinating.
Symptoms in men can include
  • A discharge from their penis;
  • A burning sensation when urinating;
  • Pain and swelling in one or both testicles (although this is less common).
Men and women can also get infected with chlamydia in their rectum, either by having receptive anal sex, or by spread from another infected site (such as the vagina). While these infections often cause no symptoms, they can cause
  • Rectal pain;
  • Discharge;
  • Bleeding.
You should be examined by your doctor if you notice any of these symptoms or if your partner has an STD or symptoms of an STD, such as an unusual sore, a smelly discharge, burning when urinating, or bleeding between periods.

How will my doctor know if I have chlamydia?

There are laboratory tests to diagnose chlamydia. Your health care provider may ask you to provide a urine sample or may use (or ask you to use) a cotton swab to get a sample from your vagina to test for chlamydia.

Can chlamydia be cured?

Yes, chlamydia can be cured with the right treatment. It is important that you take all of the medication your doctor prescribes to cure your infection. When taken properly it will stop the infection and could decrease your chances of having complications later on. Medication for chlamydia should not be shared with anyone.
Repeat infection with chlamydia is common. You should be tested again about three months after you are treated, even if your sex partner(s) was treated.

I was treated for chlamydia. When can I have sex again?

You should not have sex again until you and your sex partner(s) have completed treatment. If your doctor prescribes a single dose of medication, you should wait seven days after taking the medicine before having sex. If your doctor prescribes a medicine for you to take for seven days, you should wait until you have taken all of the doses before having sex.

What happens if I don't get treated?

The initial damage that chlamydia causes often goes unnoticed. However, chlamydia can lead to serious health problems.
If you are a woman, untreated chlamydia can spread to your uterus and fallopian tubes (tubes that carry fertilized eggs from the ovaries to the uterus), causing pelvic inflammatory disease (PID). PID often has no symptoms, however some women may have abdominal and pelvic pain. Even if it doesn’t cause symptoms initially, PID can cause permanent damage to your reproductive system and lead to long-term pelvic pain, inability to get pregnant, and potentially deadly ectopic pregnancy (pregnancy outside the uterus).
Men rarely have health problems linked to chlamydia. Infection sometimes spreads to the tube that carries sperm from the testicles, causing pain and fever. Rarely, chlamydia can prevent a man from being able to have children.
Untreated chlamydia may also increase your chances of getting or giving HIV – the virus that causes AIDS.

Main types of sexually transimitted diseases

Main types of sexually transimitted diseases
Sexually transmitted infections include:
  • Chlamydia is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis. In women, symptoms may include abnormal vaginal discharge, burning during urination, and bleeding in between periods, although most women do not experience any symptoms. Symptoms in men include pain when urinating, and abnormal discharge from their penis. If left untreated in both men and women, Chlamydia can infect the urinary tract and potentially lead to pelvic inflammatory disease (PID). PID can cause serious problems during pregnancy and even has the potential to cause infertility. It can cause a woman to have a potentially deadly ectopic pregnancy, in which the child is born outside of the uterus. However, Chlamydia can be cured with antibiotics.

  • The two most common forms of herpes are caused by infection with herpes simplex virus (HSV). HSV-1 is typically acquired orally and causes cold sores, HSV-2 is usually acquired during sexual contact and affects the genitals, however either strain may affect either site. Some people are asymptomatic or have very mild symptoms. Those that do experience symptoms usually notice them 2 to 20 days after exposure which last 2 to 4 weeks. Symptoms can include small fluid-filled blisters, headaches, backaches, itching or tingling sensations in the genital or anal area, pain during urination, Flu like symptoms, swollen glands, or fever. Herpes is spread through skin contact with a person infected with the virus. The virus affects the areas where it entered the body. This can occur through kissing, vaginal intercourse, oral sex or anal sex. The virus is most infectious during times when there are visible symptoms, however those who are asymptomatic can still spread the virus through skin contact. The primary attack is the most severe because the body does not have any antibodies built up. After the primary attack, one might have recurring attacks that are milder or might not even have future attacks. There is no cure for the disease but there are antiviral medications that treat its symptoms and lower the risk of transmission (Valtrex). Although HSV-1 is typically the "oral" version of the virus, and HSV-2 is typically the "genital" version of the virus, a person with HSV-1 orally CAN transmit that virus to their partner genitally. The virus, either type, will settle into a nerve bundle either at the top of the spine, producing the "oral" outbreak, or a second nerve bundle at the base of the spine, producing the genital outbreak.


  • The human papillomavirus (HPV) is the most common STI in the United States. There are more than 40 different strands of HPV and many do not cause any health problems. In 90% of cases the body’s immune system clears the infection naturally within 2 years. Some cases may not be cleared and can lead to genital warts (bumps around the genitals that can be small or large, raised or flat, or shaped like cauliflower) or cervical cancer and other HPV related cancers. Symptoms might not show up until advanced stages. It is important for women to get pap smears in order to check for and treat cancers. There are also two vaccines available for women (Cervarix andGardasil) that protect against the types of HPV that cause cervical cancer. HPV can be passed through genital-to-genital contact as well as during oral sex. It is important to remember that the infected partner might not have any symptoms.

  • Gonorrhea is caused by bacterium that lives on moist mucous membranes in the urethra, vagina, rectum, mouth, throat, and eyes. The infection can spread through contact with the penis, vagina, mouth or anus. Symptoms of Gonorrhea usually appear 2 to 5 days after contact with an infected partner however, some men might not notice symptoms for up to a month. Symptoms in men include burning and pain while urinating, increased urinary frequency, discharge from the penis (white, green, or yellow in color), red or swollen urethra, swollen or tender testicles, or sore throat. Symptoms in women may include vaginal discharge, burning or itching while urinating, painful sexual intercourse, severe pain in lower abdomen (if infection spreads to fallopian tubes), or fever (if infection spreads to fallopian tubes), however many women do not show any symptoms.[50] There are some antibiotic resistant strains for Gonorrhea but most cases can be cured with antibiotics.

Secondary syphilis
  • Syphilis is an STI caused by a bacterium. Untreated, it can lead to complications and death. Clinical manifestations of syphilis include the ulceration of the uro-genital tract, mouth or rectum; if left untreated the symptoms worsen. In recent years, the prevalence of syphilis has declined in Western Europe, but it has increased in Eastern Europe (former Soviet states). A high incidence of syphilis can be found in places such as Cameroon, Cambodia, Papua New Guinea. Syphilis infections are increasing in the United States.
  • Trichomoniasis is a common STI that is caused by infection with a protozoan parasite called Trichomonas vaginalis.Trichomoniasis affects both women and men, but symptoms are more common in women. Most patients are treated with an antibiotic called metronidazole, which is very effective.


  • HIV (human immunodeficiency virus) damages the body's immune system, which interferes with its ability to fight off disease-causing agents. The virus kills CD4 cells, which are white blood cells that help fight off various infections. HIV is carried in body fluids, and is spread by sexual activity. It can also be spread by contact with infected blood, breast feeding, childbirth, and from mother to child during pregnancy. When HIV is at its most advanced stage, an individual is said to have AIDS (acquired immunodeficiency syndrome). There are different stages of the progression of and HIV infection. The stages include primary infection, asymptomatic infection, symptomatic infection, and AIDS. In the primary infection stage, an individual will have flu like symptoms (headache, fatigue, fever, muscle aches) for about 2 weeks. In the asymptomatic stage, symptoms usually disappear, and the patient can remain asymptomatic for years. When HIV progresses to the symptomatic stage, the immune system is weakened, and has a low cell count of CD4+ T Cells. When the HIV infection becomes life-threatening, it is called AIDS. People with AIDS fall prey to opportunistic infections and die as a result. When the disease was first discovered in the 1980s, those who had AIDS were not likely to live longer than a few years. There are now antiretroviral drugs (ARVs) available to treat HIV infections. There is no known cure for HIV or AIDS but the drugs help suppress the virus. By suppressing the amount of virus in the body, people can lead longer and healthier lives. Even though their virus levels may be low they can still spread the virus to others.


Unscreened

There are many species of bacteria, protozoa, fungi, and viruses, many which remain undocumented or poorly studied with regards to sexual transmission. Despite that the above include what are generally known as STIs, sexually transmission of microbes is far from limited to the above list. Since the sexual route of transmission is not considered common, and/or the microbe itself is not implicated in a major research study on disease, the following pathogens are simply not screened for in sexual health clinics. Some of these microbes are known to be sexually transmittable.
Microbes known to be sexually transmissible (but not generally considered STDs/STIs) include:
  • Marburg virus - Virus in semen for 7 weeks after clinical recovery.
  • HTLV (both types 1 and 2) - Sexually transmissible, consumption of breast milk breastfeeding, and once mistaken as a HIV, risk of leukemia.
