Why did HIV emerge?
In several articles published since 2001, Preston Marx, Philip Alcabes, and Ernest Drucker proposed that HIV emerged because of rapid serial human-to-human transmission of SIV (after a bushmeat hunter or handler became SIV-infected) through unsafe or unsterile injections.
Why did HIV become epidemic?
Amit Chitnis, Diana Rawls, and Jim Moore proposed that HIV may have emerged epidemically as a result of harsh conditions, forced labor, displacement, and unsafe injection and vaccination practices associated with colonialism, particularly in French Equatorial Africa.
How is SIV transmitted?
According to the natural transfer theory (also called "hunter theory" or "bushmeat theory"), in the "simplest and most plausible explanation for the cross-species transmission" of SIV or HIV (post mutation), the virus was transmitted from an ape or monkey to a human when a hunter or bushmeat vendor/handler was bitten or cut while hunting or butchering the animal. The resulting exposure to blood or other bodily fluids of the animal can result in SIV infection. Prior to WWII, some Sub-Saharan Africans were forced out of the rural areas because of the European demand for resources. Since rural Africans were not keen to pursue agricultural practices in the jungle, they turned to non-domesticated animals as their primary source of meat. This over-exposure to bushmeat and malpractice of butchery increased blood-to-blood contact, which then increased the probability of transmission. A recent serological survey showed that human infections by SIV are not rare in Central Africa: the percentage of people showing seroreactivity to antigens —evidence of current or past SIV infection—was 2.3% among the general population of Cameroon, 7.8% in villages where bushmeat is hunted or used, and 17.1% in the most exposed people of these villages. How the SIV virus would have transformed into HIV after infection of the hunter or bushmeat handler from the ape/monkey is still a matter of debate, although natural selection would favour any viruses capable of adjusting so that they could infect and reproduce in the T cells of a human host.
How much does HIV affect heterosexuality?
These diseases increase the probability of HIV transmission dramatically, from around 0.01–0.1% to 4–43% per heterosexual act, because the genital ulcers provide a portal of viral entry, and contain many activated T cells expressing the CCR5 co-receptor, the main cell targets of HIV.

Identification of the virus
The majority of HIV researchers agree that HIV evolved at some point from the closely related simian immunodeficiency virus (SIV), and that SIV or HIV (post mutation) was transferred from non-human primates to humans in the recent past (as a type of zoonosis). Research in this area is conducted using molecular phylogenetics, comparing viral genomic sequences to determine relatedness.
Case definition for epidemiological surveillance
The discovery of the main HIV / SIV phylogenetic relationships permits explaining broad HIV biogeography: the early centres of the HIV-1 groups were in Central Africa, where the primate reservoirs of the related SIVcpz and SIVgor viruses (chimpanzees and gorillas) exist; similarly, the HIV-2 groups had their centres in West Africa, where sooty mangabeys, which harbour the related SIVsmm virus, exist. However, these relationships do not explain more detailed patterns of biog…
