- The human immunodeficiency virus (HIV) is a type of virus called a retrovirus, which infects humans when it comes in contact with tissues such as those that line the vagina, anal area, mouth, or eyes, or through a break in the skin.
- HIV infection is generally a slowly progressive disease in which the virus is present throughout the body at all stages of the disease.
- Three stages of HIV infection have been described.
- The initial stage of infection (primary infection), which occurs within weeks of acquiring the virus, often is characterized by a flu- or mono-like illness that generally resolves within weeks.
- The stage of chronic asymptomatic infection (meaning a long duration of infection without symptoms) lasts an average of eight to 10 years.
- The stage of symptomatic infection, in which the body's immune (or defense) system has been suppressed and complications have developed, is called the acquired immunodeficiency syndrome (AIDS). The symptoms are caused by the complications of AIDS, which include one or more unusual infections or cancers, severe loss of weight, and intellectual deterioration (called dementia).
