HIV (human immunodeficiency virus) is a virus that attacks the
immune system, making it difficult for the body to fight off infection and some
diseases. HIV eventually causes AIDS (acquired immunodeficiency
syndrome).
Initial HIV symptoms are similar to those of the flu and include
fatigue, fever, weight loss, and swollen lymph nodes in the neck, armpits, or
groin. Although there currently is no cure for HIV infection, a combination of
medications called highly active antiretroviral therapy, or HAART, helps
prolong life in many people. A person with HIV infection may live for many
years before developing any signs of AIDS.
