Anyone who is sexually active can get chlamydia, but the infection is more common in some groups, including young people and gay men.

Everyone's immune system is different. This makes it difficult to predict how long this stage will last. Scientists have developed sensitive blood tests since the early days of the HIV epidemic. It's now possible to detect HIV antibodies, as well as other components of HIV, earlier than ever before.

Research has shown that females infected with chlamydia are up to five times more likely to acquire HIV if exposed to the virus. The reason for the increased risk may be that chlamydia causes a spike in the number of white blood cells at the site of infection.

People with early HIV sometimes don't show any symptoms, yet they can still transmit the virus to others. This is attributed to the fast, unrestrained viral replication that occurs in the early weeks after contracting the virus.

HIV tests are between 99% and 100% reliable. Newer, so-called combination or fourth generation tests and other lab-based tests are close to 100% accurate. Rapid or at-home tests are right around 99% of the time if you've been infected for a while. But if you were recently exposed, they may not be as trustworthy.

HIV infection is caused by the human immunodeficiency virus. You can get HIV from contact with infected blood, semen, or vaginal fluids. Most people get the virus by having unprotected sex with someone who has HIV. Another common way of getting it is by sharing drug needles with someone who is infected with HIV.

HIV isn't passed on easily from one person to another. The virus doesn't spread through the air like cold and flu viruses. HIV lives in the blood and in some body fluids. To get HIV, one of these fluids from someone with HIV has to get into your blood.

Approximately 38 million people are currently living with HIV, and tens of millions of people have died of AIDS-related causes since the beginning of the epidemic. Many people living with HIV or at risk for HIV infection do not have access to prevention, treatment, and care, and there is still no cure.

Myth: You can't catch chlamydia if you've only had sex once. Fact: If you have sex once with a partner who's got chlamydia, you've got around a 30% chance that you'll pick up the infection from that one time. That's all it takes.

Even when HIV-positive blood comes in contact with another person's open wound, it rarely leads to transmission. The Center for Disease Control in Atlanta studied thousands of such cases and determined the risk of infection is — out of 1,000.

The risk of getting HIV from a needlestick injury is less than 1%. The risk of exposure from direct skin contact with the fluid is less than 0.1%. The risk of infection from a human bite is between 0.1% and 1%.

Q: What are the chances of a man being infected after condomless sex with a woman who has HIV? In general, the risk of a man getting HIV from an HIV-positive woman during vaginal intercourse in the United States is low--probably less than 1 of 1,000 exposures will result in actual infection.

But that doesn't mean the virus is gone. It can take as long as 10 years for other symptoms to show up. During this time, if your HIV infection is untreated, the virus is still active and infecting new cells in your body.

A false negative test result occurs when the test shows negative and the person is really HIV positive. This is very rare and usually occurs during the window period when people are newly infected but the test can't quite pick up the infection. As with other types of tests, there is always be a small margin of error.
