Acute HIV Infection
Acute HIV infection is a flu-like syndrome that occurs immediately after a person contracts HIV (the human immunodeficiency virus 1). The syndrome is characterized by fever, sore throat, headache, skin rash and swollen glands (lymphadenopathy). 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.
