HIV (human immunodeficiency virus) is an infection that weakens the immune system. If the virus destroys too many white blood cells, the infected person can develop AIDS (acquired immunodeficiency syndrome). AIDS is the most severe stage of HIV infection.
HIV treatments help suppress the virus, slowing or stopping disease progression. No cure exists yet for the virus. People with HIV typically progress through 3 stages:
- Acute HIV infection—Flu-like symptoms lasting a few weeks, usually within a month of infection.
- Clinical latency—Asymptomatic phase lasting a few years to a few decades.
- AIDS—Severe, potentially fatal phase where white blood cell counts fall below 200/mm or certain opportunistic illnesses appear.
