How the virus spreads
Most new infections are transmitted by 40% of people infected with HIV — those who have not been diagnosed or have been diagnosed but are not yet receiving care.
A majority of people taking antiretroviral therapy can suppress the virus in their bodies within six months of starting therapy. When HIV-positive people maintain suppression by continuing therapy, they effectively pose no risk of infecting sexual partners and they also can live long, healthy lives, according to the CDC.
People who are newly infected and are unaware of their status led to 4% of new infections, according to CDC scientists who estimated past transmission and treatment rates.
Longer-term infected people who are unaware of their status accounted for 33.6% of new infections. People aware of their status but not receiving care accounted for 42.6%. Those receiving care but not fully suppressed accounted for 19.8% of new infections.
People living with HIV who maintain viral suppression with treatment contributed no new infections, according to CDC scientists.
