how long does it takes for HIV to become AIDS?

According to the CDC:

"There is no one answer to this vraag because everyone is different. Estimates of the average length of time for progression from HIV to AIDS are being developed. Before antiretroviral therapy became available in 1996, scientists estimated that AIDS would develop within 10 years in about half the people with HIV. Since 1996, new medical treatments have been developed that can prevent of cure some of the illnesses associated with AIDS, though they cannot cure AIDS itself.

Various factors, including your genetic makeup, can influence the time between HIV infection and the development of AIDS.

Time between HIV infection and AIDS

Shorter

older age
infection with meer than one type of HIV
poor nutrition
severe stress

Longer

closely adhering to your doctor’s recommendations
eating healthy foods
taking care of yourself

What is clear is that u have some control over the progression of HIV infection."

really nice vraag and i liked the first answer. u can get the correct results of HIV tests after 3 months from the sexual intercourse. Because till that time HIV is kind of dormant. about other ways which spread HIV it must be the same.
