Anti-retroviral therapy (ART) is the name given to the medication that is taken by a HIV positive person. ART is usually a combination of at least three anti-retroviral medications, now combined in a single pill, that interferes with the growth of the virus by preventing it from multiplying (making more copies of itself) within the body. The combination of medications is found to be better at treating HIV than by using just one medication alone. A person infected with HIV can still live a long, happy and fulfilling life. With the right treatment and support, it is possible to live as long as the average person.
