How did human immunodeficiency virus (hiv) evolve?

Evolution: It came from a simian precursor transmitted to humans by one of several mechanisms. This virus mutates continuously and the form to which it mutates which is best capable of surviving under the circumstances is the one which will be reproduced and multiply within infected cells. Unless of course you are a creationist.

How is the human immunodeficiency virus (hiv) transmitted?

Sharing body fluids: Hiv is a sexually transmitted infection. It can also be spread by contact with infected blood, or from mother to child during pregnancy, childbirth or breast-feeding. It can take years before HIV weakens the immune system to the point that the patient has aids. There is no cure for hiv/aids, but there are medications that can dramatically slow the progression of the disease.

Sharing contaminated injection drug needles / syringes is another way to transmit HIV. Always use clean needles. Always used condoms with anal and vaginal sex.

Get tested.: The only way to know if you have HIV is to get tested for hiv. Please visit with a clinic or doctor and have testing performed. The clinic or doctor will explain the results and be able to answer questions. To decrease risk, always use clean (single use) needles for injection drugs and always have 'safe' sex with a condom and spermicidal lubricant. Be well.

A 41-year-old member asked:

Human immunodeficiency virus--can it mutate?

1 doctor answer3 doctors weighed in
Dr. Joel Gallant
Infectious Disease 36 years experience
Yes: Hiv mutates in response to HIV therapy. If you're being treated without a complete response (partial suppression), the virus can mutate so it can replicate in the presence of the drugs. This usually happens in people who don't take their medications properly. They can then transmit the mutant virus to others. Spontaneous mutation (mutation independent of therapy) has not been a big problem.

Blood: Tainted blood transfusions are the easiest way to become infected with hiv. In the developed world, all blood is screened for HIV and blood transfusions are safe. Other high risk activities include sharing needles for intravenous drug use with infected individuals and having unprotected receptive anal intercourse with an HIV infected person.
