Analysis of HIV-1 recent infections and hotspot areas in a bordering area in Yunnan Province, China.

ABSTRACT:

Background

Honghe Prefecture, located on the China-Vietnam border, has long suffered from HIV-1. To accurately assess the HIV-1 prevalence situation and promote precise prevention and treatment of AIDS, a recent infection surveillance was conducted to explore the at-risk subpopulations and hotspot areas of HIV-1 transmission in Honghe Prefecture.

Methods

Combined with the recent infection testing algorithm, HIV-1 recency assay was used to differentiate recent HIV-1 infections among newly reported HIV-1 cases in Honghe Prefecture from 2021 to 2022. Factors associated with recent HIV-1 infection were analyzed by logistic regression. The hotspot areas of recent infections were analyzed by spatial scanning statistics.
