AIDS is a worldwide pandemic with no current cure or treatment. Learn more about the challenges people living with HIV/AIDS have to face, their experiences living within their communities, and the medical efforts to find them a cure.
HIV/AIDS has become a chronic rather than an acutely fatal disease in many areas of the world. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype.
After the diagnosis of AIDS, if treatment is not available, survival ranges between 6 and 19 months. If treatment is started late in the infection, prognosis is not as good, for example, if treatment is begun following the diagnosis of AIDS, life expectancy is ~10–40 years.
As of 2012, approximately 35.3 million people have HIV worldwide with the number of new infections that year being about 2.3 million. This is down from 3.1 million new infections in 2001.
South Africa has the largest population of people with HIV of any country in the world at 5.9 million. HIV/AIDS research includes all medical research which attempts to prevent, treat, or cure HIV/AIDS along with fundamental research about the nature of HIV as an infectious agent and AIDS as the disease caused by HIV.
