HIV/AIDS in India is an epidemic. The National AIDS Control Organisation (NACO) estimated that 2.14 million people lived with HIV/AIDS in India in 2017. Despite being home to the world's third-largest population of persons with HIV/AIDS (as of 2018, with South Africa and Nigeria having more), the AIDS prevalence rate in India is lower than that of many other countries. In 2016, India's AIDS prevalence rate stood at approximately 0.30%—the 80th highest in the world. Treatment of HIV/AIDS is primarily via a "drug cocktail" of antiretroviral drugs and education programs to help people avoid infection.
