If you take an HIV test during the window period, it’s likely you’ll receive a negative result. But you can still transmit the virus to others. If you think you may have been exposed to HIV, but tested negative during this time, you should repeat the test in three months to confirm.
Definition (CSP) any state of infection accompanied by evidence of HIV in the body (positive test for HIV genome, cDNA, proteins, antigens, or antibodies); may be medically asymptomatic or symptomatic; use AIDS when appropriate.

The HIV enzyme reverse transcriptase converts the viral RNA into DNA, which is compatible to human genetic material, when the virus is inside the cell. This DNA is transported to the cell’s nucleus, where it is spliced into human DNA by the HIV enzyme integrase. The HIV DNA is known as provirus after it is integrated.

Universal precautions within the health care environment are believed to be effective in decreasing the risk of HIV. Intravenous drug use is an important risk factor and harm reduction strategies such as needle-exchange programs and opioid substitution therapy appear effective in decreasing this risk.
HIV-1 originated in Central Africa during the first half of the 20th century when a closely related chimpanzee virus first infected people. The global spread of HIV-1 began in the late 1970s, and AIDS was first recognized in 1981. In 2015, about 36.7 million people were living with HIV infection worldwide, there were 1.1 million AIDS-related deaths, and 2.1 million people were newly infected.
The sexual partners and drug injecting partners of people diagnosed with HIV infection have an increased probability of also being HIV-positive. WHO recommends assisted HIV partner notification services as a simple and effective way to reach these partners, many of whom are undiagnosed and unaware of their HIV exposure, and may welcome support and an opportunity to test for HIV.

Acute retroviral syndrome usually begins within 1 to 4 wk of infection and usually lasts 3 to days. Symptoms and signs are often mistaken for infectious mononucleosis or benign, nonspecific viral syndromes and may include fever, malaise, fatigue, several types of dermatitis, sore throat, arthralgias, generalized lymphadenopathy, and septic meningitis.
Many HIV-positive people are unaware that they are infected with the virus. For example, in 2001 less than 1% of the sexually active urban population in Africa had been tested, and this proportion is even lower in rural populations. Furthermore, in 2001 only 0.5% of pregnant women attending urban health facilities were counselled, tested or receive their test results. Again, this proportion is even lower in rural health facilities. Since donors may therefore be unaware of their infection, donor blood and blood products used in medicine and medical research are routinely screened for HIV.

If people at low risk have a negative test result, the screening test is not repeated unless their risk status changes. If people at the highest risk have a negative test result (especially if they are sexually active, have several partners, or do not practice safe sex), testing should be repeated every 6 to 12 months.
General Health – it is crucial to take medication correctly and take steps to avoid illness. People living with HIV should seek to improve their general health by regularly exercising, eating healthfully, and not smoking.
