HIV is a virus that affects the immune system, specifically the CD4 cells. The CD4 cells help protect the body from illness. Unlike other viruses that the immune system can normally fight off, HIV can’t be eliminated by the immune system.
The symptoms of HIV can vary greatly from person to person. No two men with HIV will likely experience the exact same symptoms. However, an HIV infection in men will generally follow this pattern:
- acute illness
- asymptomatic period
- advanced infection
