Abstract Objective To assess the spatial pattern and determinants of HIV infection in India. Methods We conducted a secondary data analysis using the National Family Health Survey‐4 data obtained from the Demographic Health Survey programme. We accounted for clustering and stratification in the sampling design using the svyset command. Spatial analysis was performed by generating the Moran’s I statistic and local indicators for spatial association (LISA) maps. Logistic regression was performed to identify the determinants of HIV infection. Results 230 213 individuals were included. Prevalence of HIV infection in India was 0.24% (95% CI: 0.21%–0.28%). Being separated/widowed/divorced (aOR = 2.58, 95% CI: 1.22–5.40), living in an urban area (aOR = 2.46, 95% CI: 1.79–3.37), being resident in the North‐Eastern (aOR = 4.25, 95% CI: 2.60–6.93), Southern (aOR = 3.13, 95% CI: 1.99–4.91) or Western region (aOR = 2.17, 95% CI: 1.08–4.33), having a history of multiple sexual partners (aOR = 1.99, 95% CI:1.42–2.79), a suspected STI (aOR = 2.32, 95% CI: 1.38–3.90) or self‐reported TB (aOR = 7.80, 95% CI: 2.52–24.05) were significantly in association with HIV infection. Moran’s I was 0.377, suggesting positive spatial autocorrelation. The LISA cluster map indicated 60 hotspot districts in India, mostly in southern states such as Karnataka, Andhra Pradesh and Telangana followed by north‐eastern states such as Nagaland, Manipur, Mizoram, Tripura and Assam. Conclusion HIV infection among adults aged 15–54 years in India is spatially clustered with the majority occurring in southern and north‐eastern states. Hence, region‐ or district‐specific strategies with focused interventions should be adopted.
