Acute HIV infection
-
Also known as primary HIV infection or acute retroviral syndrome.
The period of rapid HIV replication that occurs 2 to 4 weeks after infection by HIV.
Acute HIV infection is characterized by a drop in CD4 cell counts and an increase in HIV levels in the blood.
Some, but not all, individuals experience flu-like symptoms during this period of infection. These symptoms, collectively known as AIDS-related complex, can include fever, inflamed lymph nodes, sore throat, and rash. These symptoms may last from a few days to 4 weeks and then go away.Reference: AIDSinfo. Glossary. Internet. Accessed August 7, 2009.
