when do you know if you have hiv?

First stages of HIV infection Within two to four weeks after infection, you may experience flu-like symptoms such as fatigue, fever, sore throat, swollen lymph nodes, headache, loss of appetite or skin rash. During this period, the immune system is learning to recognize HIV.

Current tests typically become positive within 3–6 weeks of infection and 1–3 weeks after the onset of acute HIV symptoms [1]. While detection of early infection is a strength of these tests, it creates challenges in identifying persons with very early HIV.

Most people experience a short flu-like illness 2 to 6 weeks after HIV infection, which lasts for a week or 2. After these symptoms disappear, HIV may not cause any symptoms for many years, although the virus continues to damage your immune system. This means many people with HIV do not know they're infected.

This is the virus that causes AIDS. These signs and symptoms of acute HIV infection can begin a few days after you are exposed to HIV and usually last for about 14 days. They could last for just a few days, or they could last for several months. You might not realize your illness is acute HIV infection.

5. How long does it take to develop signs of HIV? Persons with HIV can develop signs of infection anywhere from months to years after being infected. About half of the people with HIV develop AIDS within 10 years, but the time between infection with HIV and the onset of AIDS can vary greatly.

Even without treatment, it takes a long time for HIV to progress to AIDS—usually 10 to 12 years. When HIV is diagnosed before it becomes AIDS, medicines can slow or stop the damage to the immune system.

HIV tests detect antibodies — the immune system's response to infection. For the majority of people, HIV testing will be accurate at four to six weeks after possible infection. However, for some people it may take longer — up to three months — for detectable antibodies to develop.

Acute HIV infection, also known as an early or primary retroviral infection, is a condition that develops within two to four weeks of contracting human immunodeficiency virus (HIV). Symptoms of acute HIV infection are similar to other viral infections, such as the flu or mononucleosis (mono or glandular fever).

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. After up to 10 years with an untreated HIV infection, the virus has damaged your immune system.

Most people infected with HIV experience a short, flu-like illness that occurs 2-6 weeks after infection. After this, HIV may not cause any symptoms for several years. It's estimated up to 80% of people who are infected with HIV experience this flu-like illness.

Within two to four weeks after infection, you may experience flu-like symptoms such as fatigue, fever, sore throat, swollen lymph nodes, headache, loss of appetite or skin rash. During this period, the immune system is learning to recognize HIV. Primary infection refers to the time when you're first infected with HIV.

It can take 3 months for HIV to show up on a test, but it only takes a matter of days to a few weeks for STDs like gonorrhea, chlamydia, and syphilis to show up.

Symptom 1: Fever The fever, usually one of the first symptoms of HIV, is often accompanied by other mild symptoms, such as fatigue, swollen lymph glands, and a sore throat. At this point the virus is moving into the blood stream and starting to replicate in large numbers.

A human immunodeficiency virus (HIV) test detects HIV antibodies or antigens, or the genetic material (DNA or RNA) of HIV in blood or another type of sample. This determines whether an HIV infection is present (HIV-positive). ELISA results are usually available in 2 to 4 days.

One recommended strategy is to get tested 2-4 weeks, 3 months, and 6 months after a risky exposure. Using a sensitive antigen/antibody HIV test, of those who are infected, most will test positive at 1 month; almost all will test positive at 3 months; and the rest will test positive at 6 months.

This test looks for HIV antibodies in your blood or saliva. Your immune system makes antibodies when you are exposed to bacteria or viruses, like HIV. An HIV antibody test can determine if you have HIV from 3–12 weeks after infection.
