Maharashtra has the highest number of people living with HIV (PLHIV) in India at 330,000, followed by Andhra Pradesh, Karnataka, Telangana, West Bengal, Tamil Nadu, Uttar Pradesh and Bihar. These eight states account for about three-fourths of India's total estimated PLHIV. HIV was first reported in 1981 in the United States and the first cases in India were detected in Chennai in 1986. The National AIDS Control Programme was initiated in 1987 to raise awareness and establish surveillance systems. It has since expanded to include targeted interventions, treatment, and efforts to reduce stigma and discrimination.
