They believed that the heterosexual epidemic could be contained by focusing prevention efforts on persuading the so-called core transmitters—people such as sex workers and truck drivers, known to have multiple sex partners—to use condoms.
These factors retarded prevention campaigns in many countries for more than a decade.
AIDS first was identified in the United States and France in 1981, principally among homosexual men.
Then in 19, heterosexual Africans also were diagnosed.
The hunters then became infected with HIV and passed on the disease to other humans through bodily fluid contamination. HIV made the leap from rural isolation to rapid urban transmission as a result of urbanization that occurred during the 20th century.
There are many reasons for which there is such prevalence of AIDS in Africa.
Trade along the rivers could have spread the virus, which built up slowly in the human population.
By the 1960s, about 2,000 people in Africa may have had HIV, The first epidemic of HIV/AIDS is believed to have occurred in Kinshasa in the 1970s, signalled by a surge in opportunistic infections such as cryptococcal meningitis, Kaposi's sarcoma, tuberculosis, and pneumonia.Some areas of the world were already significantly impacted by AIDS, while in others the epidemic was just beginning.The virus is transmitted by bodily fluid contact including the exchange of sexual fluids, by blood, from mother to child in the womb, and during delivery or breastfeeding.Acquired immunodeficiency syndrome (AIDS) is a fatal disease caused by the slow-acting human immunodeficiency virus (HIV).The virus multiplies in the body until it causes immune system damage, leading to diseases of the AIDS syndrome.Unfortunately though, the majority of people in need of treatment are still not receiving it, and campaigns to prevent new infections ... The earliest known cases of human HIV infection have been linked to western equatorial Africa, probably in southeast Cameroon where groups of the central common chimpanzee live. revealed that all HIV-1 strains known to infect humans, including HIV-1 groups M, N, and O, were closely related to just one of these SIVcpz lineages: that found in P. Current hypotheses also include that, once the virus jumped from chimpanzees or other apes to humans, the colonial medical practices of the 20th century helped HIV become established in human populations by 1930.
