Trend estimates show Nagaland’s adult HIV prevalence among the 15-49 age group has remained above 1.3% for over a decade, in contrast to India’s steady decline from 0.32% in 2010 to 0.2% in 2025.
Age-wise data (April 2025-March 2026) revealed that the 25-34 age group was the most affected, accounting for 38.47% of cases, followed by 35-49 years (33.47%). The 15-24 age group accounted for 15.32%, children below 14 years 4.39%, and those aged 50 and above 8.35%.
In terms of transmission, heterosexual contact remained the leading mode at 83.08%, followed by syringe and needle sharing (10.99%), parent-to-child transmission (4.64%), homo/bisexual transmission (0.88%), blood-related transmission (0.05%) and unknown causes (0.36%).
