To identify longitudinal shifts in HIV-1 transmission dynamics and map evolving geographical transmission hotspots across urban zones.
Analyzed HIV-1 pol sequences from 2,469 individuals living with HIV categorized by residential zones into central, suburban, and outer suburban areas between 2018 and 2020.
Reconstructed molecular networks for three predominant genotypes (CRF01_AE, CRF07_BC, and CRF55_01B) to evaluate clustering rates, assortativity coefficients, and transmission intensity matrices.
Clustering rates showed no significant differences across central, suburban, and outer suburban zones (44.5%, 40.6%, vs. 45.7%; p = 0.184), yet transmission hotspots for CRF01_AE and CRF55_01B shifted toward outer suburban areas.
Individuals preferentially formed transmission links within their local geographic area (assortativity coefficient = 0.227, p < 0.001), especially for CRF01_AE (assortativity = 0.512, p < 0.001; intra-area intensity = 69.2%).
Intra-area transmission in the central area decreased from 74.5% to 30.2%, whereas intra- and inter-area transmission involving the outer suburban area increased from 23.1% to 38.2%.

Implication

Spatiotemporal molecular network study reveals shifts in transmission hotspots toward outer suburban areas among people with HIV-1, suggesting a need for expanded regional prevention strategies.
