As a result, it infects far fewer people, and is mainly found in a few countries in West Africa like Mali, Mauritania, Nigeria and Sierra Leone.

Later research established these theories were mostly correct: This theory was later dubbed "Heart of Darkness" by Jim Moore, [33] alluding to the book of the same title written by Joseph Conradthe main focus of which is colonial abuses in equatorial Africa.

He was incorrectly called "Patient Zero" because at least 40 of the people known to be infected by HIV in had had sex with him, or with someone who had sexual intercourse with him.

The sample was retrospectively analysed and HIV detected. Overview Today, HIV human immunodeficiency virusremains one of the largest pandemics in the world. Inscientists discovered the virus that causes AIDS.

The resulting exposure to blood or other bodily fluids of the animal can result in SIV infection. William Darrow of the Centers for Disease Control. These HIV-2 strains are probably dead-end infectionsand each of them is most closely related to SIVsmm strains from sooty mangabeys living in the same country where the human infection was found.

During this time, more than million blood components were transfused in the United States. The U.S. Public Health Service asks "members of groups at increased risk for AIDS" to stop donating blood. Experts confirm the heterosexual spread of AIDS in Africa.
