Answer

Prevention of exposure to HIV and HHV-8 is the most effective method of preventing Kaposi sarcoma. Sexual abstinence, monogamy, or condom use and avoidance of IV drug use or use of sterile needles and syringes are the best methods.

Similar measures are recommended for those who are already infected with HIV, to prevent infecting others and to avoid co-infection with other sexually transmitted and hematogenous infections. The use of antiretroviral therapy decreases risk of Kaposi sarcoma in patients already infected with HIV and may be equally effective in treating Kaposi sarcoma. [60]
