HIV The Unveiling of the computer virusScientists believe HIV originated from a chimpanzee in Western Africa. The best approved theory closely the source of HIV is that it is a descendant of a related virus, simian Immunodeficiency Virus (SIV), which infects monkeys (Perlin, David, and Cohen, Ann, 2002, 79-92).People may have come in affair with HIV from hunting and eating infected animals (Perlin, David, and Cohen, Ann, 2002, 79-92). The earliest known theatrical role of infection with HIV in a hu soldiery was identified in a blood strain collected in 1959 from a man in Democratic Republic of the Congo. Genetic analysis of this blood sample suggested that HIV-1 may have expanded from a single virus in the late 1940s to early 1950s (The back up Institute.org, 2011).Background cultivationIn 1982, public health officials began to use the name acquired immunodeficiency syndrome or AIDS, to portray the occurrences of opportunistic infections, Kaposis sarcoma, and Pneumocystis jir ovecii pneumonia in previously healthy people. Formal tracking of AIDS cases also began in the United States In 1982. In 1983, scientists discovered the virus that caused AIDS. The virus was first named HTLV-III/LAV (human T-cell lymphotropic virus type III/lymphadenopathy associated virus) by an international scientific committee. The name for HIV was later changed to Human Immunodeficiency Virus (The AIDS Institute.org, 2011).There atomic number 18 two species of the virus, HIV-1 and HIV-2. The first developed from a Simian Immunodeficiency Virus (SIV) found in chimpanzees, whereas the second came from an SIV in a type of monkey called the sooty mangabey. HIV-1, which is responsible for the majority of AIDS cases worldwide, is divide into three groupsthe main group M, the much r arer gro... ...M), predominantly black men, are most seriously affected by HIV. 1,144,500 people over the advance of 13 are living with HIV, including 15.8 percent who are unaware. Over the aside deca de, the number of HIV has risen, while the annual rate of new infections has remained undifferentiated (AIDS.gov, 2012).HIV disease prevails as a serious health cater for parts of the world. Worldwide, there were about 2.5 million new cases of HIV in 2011. Around 34.2 million people are living with HIV round the world. In 2010, there were about 1.8 million deaths in people with AIDS. close 30 million people with AIDS have died worldwide since the pestilential began. Although Sub-Saharan Africa bears the biggest burden of HIV/AIDS, countries such as South and south-east Asia, Eastern Europe and Central Asia, and parts of Latin America are significantly affected by HIV and AIDS (CDC.gov, 2013).
