Overview
Acquired immunodeficiency syndrome (AIDS) is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). By damaging your immune system, HIV interferes with your body's ability to fight infection and disease.
HIV is a sexually transmitted infection (STI). It can also be spread by contact with infected blood and from illicit injection drug use or sharing needles. It can also be spread from mother to child during pregnancy, childbirth or breastfeeding. Without medication, it may take years before HIV weakens your immune system to the point that you have AIDS.
There's no cure for HIV/AIDS, but medications can control the infection and prevent progression of the disease. Antiviral treatments for HIV have reduced AIDS deaths around the world, and international organizations are working to increase the availability of prevention measures and treatment in resource-poor countries
Symptoms
The symptoms of HIV and AIDS vary, depending on the phase of infection.
Primary infection (Acute HIV)
Some people infected by HIV develop a flu-like illness within 2 to 4 weeks after the virus enters the body. This illness, known as primary (acute) HIV infection, may last for a few weeks.
Possible signs and symptoms include:
FeverHeadacheMuscle aches and joint painRashSore throat and painful mouth soresSwollen lymph glands, mainly on the neckDiarrheaWeight lossCoughNight sweats
These symptoms can be so mild that you might not even notice them. However, the amount of virus in your bloodstream (viral load) is quite high at this time. As a result, the infection spreads more easily during primary infection than during the next stage.
Clinical latent infection (Chronic HIV)
In this stage of infection, HIV is still present in the body and in white blood cells. However, many people may not have any symptoms or infections during this time.
