HIV is a virus that damages the immune system. The immune system helps the body fight off infections. Untreated HIV infects and kills CD4 cells, which are a type of immune cell called T cells. Over time, as HIV kills more CD4 cells, the body is more likely to get various types of infections and cancers.
HIV is transmitted through bodily fluids that include:
vaginal and rectal fluids
The virus doesn’t spread in air or water, or through casual contact.
HIV is a lifelong condition and currently there is no cure, although many scientists are working to find one. However, with medical care, including treatment called antiretroviral therapy, it’s possible to manage HIV and live with the virus for many years.
Without treatment, a person with HIV is likely to develop a serious condition called AIDS. At that point, the immune system is too weak to fight off other diseases and infections. Untreated, life expectancy with AIDS is about three yearsTrusted Source. With antiretroviral therapy, HIV can be well-controlled and life expectancy can be nearly the same as someone who has not contracted HIV.
It’s estimated that 1.1 million Americans are currently living with HIV. Of those people, 1 in 5 don’t know they have the virus.HIV can cause changes throughout the body. Learn about the effects of HIV on the different systems in the body.
