Infection, acute HIV

14 views

The body's initial reaction to infection by the HIV virus.

Acute HIV infection is a flu-like syndrome that occurs immediately after a person contracts HIV (the human immunodeficiency virus 1, the agent that causes AIDS).

The syndrome is characterized by fever, sore throat, headache, skin rash and swollen glands (lymphadenopathy).</P> This syndrome precedes seroconversion -- the development of detectable antibodies to HIV in the blood as a result of the infection.

It normally takes several weeks to several months for antibodies to the virus to develop after HIV transmission.

When antibodies to HIV appear in the blood, a person will test positive in the standard ELISA test for HIV.
