HAART stands for Highly Active Antiretroviral Therapy, a treatment regimen used to manage HIV infection. It involves a combination of at least three antiretroviral drugs that work together to suppress the virus, helping to improve the immune system and reduce the risk of AIDS and other complications. This therapy has significantly changed the outlook for individuals living with HIV, allowing many to lead healthier lives. By lowering the viral load in the body, HAART can help prevent the transmission of the virus to others, making it a crucial component in the fight against the HIV/AIDS epidemic.
