Step 5: Effective Drug Treatment
Over the course of the HIV/AIDS epidemic, effective medications have been developed that prevent or greatly delay the onset of AIDS for HIV-positive people. These combinations of medications are called antiretroviral therapy (ART). Though these medications are not able to eliminate the virus or cure an HIV-positive person, they work by controlling the virus so that there are very low levels of virus in the body. An HIV-positive individual can live a long, healthy life if they can access and adhere to an ART drug regimen.
Since the HIV virus attacks immune system cells called CD4 cells, the number of CD4 cells a person has is an important clinical indicator that can show how well treatment is working. Historically, the CDC had made recommendations that only people with certain low levels of CD4 cells should be given ART drug regimens. However, the current clinical recommendation is that all people living with HIV, regardless of the count of their CD4 cells, should start ART as soon as they are diagnosed. According to the CDC, as of 2011, about 37% of people in the U.S. infected with HIV were prescribed antiretroviral therapy.
