Acute HIV infectionAlternative namesPrimary HIV infection; HIV seroconversion syndrome; Acute retroviral syndromeDefinitionAcute HIV infection is caused by the human immunodeficiency virus (HIV), a virus that gradually destroys the immune system.Causes, incidence, and risk factorsPrimary or acute HIV infection is a condition that occurs 2 to 4 weeks after infection by the HIV virus. The virus, called human immunodeficiency virus or HIV, is spread by intimate sexual contact, injection drug use in which contaminated needles and syringes are used, contaminated blood transfusions and blood products, through the placenta from the mother to the fetus, and rarely through breastfeeding. Acute HIV infection can resemble infectious mononucleosis , flu , or other virual syndromes. Typical symptoms include fever, headache, fatigue, and swollen lymph nodes . People may also experience aching muscles and a rash that occurs anywhere on the body and may change locations. These symptoms may last from a few days to 4 weeks, and then subside. After an infection with HIV, antibodies to the virus can be detected in the blood. This is called seroconversion. HIV seroconversion (converting from HIV negative to HIV positive) usually occurs within 3 months of exposure, but on rare occasions may occur up to a year after exposure. Following the acute infection, there may be no further evidence of illness for the next decade. Acute HIV infection can, but does not always, progress to early symptomatic HIV infection and to advanced HIV disease ( AIDS ). It cannot be assumed that all people infected with HIV will inevitably progress to AIDS, but time has shown that the vast majority do. To date there are a small number of people who have unquestionably tested positive for HIV, but no longer test positive and have absolutely no signs of disease. These numbers are extremely small, but they provide evidence that the human body may be capable of eliminating the disease. These people are being carefully watched and studied. HIV has spread throughout the United States and other countries. Higher concentrations of the disease are found in large metropolitan centers, inner cities, and among certain populations with high-risk behaviors.
SymptomsNote: At the time of diagnosis with HIV, many people have not experienced any symptoms. Any of the following symptoms may occur:
Signs and tests
TreatmentPeople with HIV infection need to receive education about the disease and its treatment so they can be active partners in decision making with the health care provider. Recent studies show that aggressive early treatment of HIV infection with HIV medications can slow the progression of disease. You should discuss this option with your health care provider. Certain healthful practices should be followed in the early stages of HIV infection:
Support GroupsThe stress of illness can often be reduced by joining a support group, where members share common experiences and problems. See AIDS - support group .Expectations (prognosis)HIV is a long-term medical condition that can be treated but not yet cured. There are effective means of preventing complications and delaying (but not preventing) progression to AIDS. At the present time, not all cases of HIV have progressed to AIDS, but time has shown that the vast majority do. Complications
Calling your health care providerCall for an appointment with your health care provider if you have had a possible or actual exposure to AIDS or HIV infection; or if you are at risk and have had symptoms suggestive of acute HIV infection. PreventionFor a comprehensive discussion, see the prevention section in AIDS . Safer sex behaviors may reduce the risk of acquiring the infection. There is a risk of acquiring the infection even if "safe sex" is practiced. Abstinence is the only sure way to prevent sexual transmission of the HIV virus. General guidelines:
