This is a timeline of HIV/AIDS, including but not limited to cases before 1980. Pre-1980s See also: Timeline of early HIV/AIDS cases Researchers estimate that some time in the early 20th century, a form of Simian immunodeficiency virus found in chimpanzees (SIVcpz) first entered humans in Central Africa and began circulating in Léopoldville (modern-day Kinshasa) by the 1920s. This gave rise ...
HIV-1 group M (responsible for the global pandemic) is estimated to have emerged in humans around 1920 near Kinshasa, then part of the Belgian Congo.This estimation was the result of time-scaled evolutionary models being applied to modern samples and retrieved early samples of HIV-1 (M).
Eastern Europe and central Asia has observed a 43% increase in new HIV infections and 32% increase in AIDS-related deaths since 2010, the highest of all global regions. [228] These infections are predominantly distributed in persons who inject drugs, with gay men and other men who have sex with men or persons who engage in transaction sex the ...
While HIV is highly virulent, transmission through sexual contact does not occur when an HIV-positive individual maintains a consistently undetectable viral load (<50 copies/ml) due to antiretroviral treatment. This concept was first proposed by the Swiss Federal Commission for AIDS/HIV in 2008 in what is known as the Swiss Statement.
The history of syphilis has been well studied, but the exact origin of the disease remains unknown. [3] It appears to have originated in both Africa and America.

In some areas of Europe, such as the Baltic countries, the most common route of HIV transmission is through injecting drug use and heterosexual sex, including paid sex. [1] The adult (15–49) prevalence in Europe in 2018 varied from a high of 1.20% in Russia to a low of 0.1% in eleven countries. [2]
Young people with polio receiving physiotherapy in the 1950s. The social history of viruses describes the influence of viruses and viral infections on human history. Epidemics caused by viruses began when human behaviour changed during the Neolithic period, around 12,000 years ago, when humans developed more densely populated agricultural communities.
