Understanding The Evolution, Life History, And Aids,...

Ebola and HIV Ebola, and AIDS, Acquired Immunodeficiency Syndrome, are both dangerous zoonotic diseases that originated in Sub-Saharan Africa. AIDS, the result of HIV, human immunodeficiency virus, has been an ongoing pandemic for decades. Meanwhile, the first Ebola case was recognized in the 1976 and has incurred severe sporadic outbreaks but has been controlled (Rajak, 2015). While both rapidly mutating RNA viruses, several key factors have allowed AIDS, to become a worldwide pandemic while Ebola has been controlled at present (Calmy, 2015). Understanding the evolution, life history, and the socio-economic factors that affect the proliferation of each disease allows us to understand how they arose when they did and why Ebola is controlled and AIDS isn’t. To start, Ebola and HIV are both zoonotic RNA viruses that underwent evolution and mutation to emerge from the jungle and morph into the deadly diseases they are today. It is thought that Ebola originated in Africa fruit bats, and was transmitted to humans for the first time through contact with bodily fluids from the bats, either as blood or saliva. Transmission to humans most often occurs through hunting and preparation of infected bushmeat, or consumption of fruit contaminated with bat saliva. This was made possible because of human encroachment on natural areas and bat habitats (Alexander, 2015). Once present in the human population more hosts allowed for extensive mutation. This is because RNA viruses use RNAShow MoreRelatedHiv And The Human Immunodeficiency Virus3032 Words   |  13 PagesThe Human Immunodeficiency Virus, also known as HIV, was discovered by Dr. Robert Gallo and Dr. Luc Montagnier.
