Antivirals are medications that keep viruses from reproducing inside the body. To date, relatively few effective antiviral drugs have been developed. It is difficult to create effective antiviral medications because viruses are tiny (smaller than bacteria and fungi) and use a cellâs metabolic pathways to replicate.
Improving Health Outcomes, Preventing New Infections. HIV is a virus that can multiply quickly and damage the bodyâs immune system, making it hard to fight off infections and cancers. While no cure exists for HIV infection, effective treatment is available. Today, there are more than 30 antiretroviral drugs approved by the Food and Drug Administration (FDA) to treat HIV infection. When used consistently, antiretroviral therapy (ART) can reduce the amount of virus in the blood and body fluids to very low or undetectable levels (known as viral suppression).
