Late HIV Diagnosis and Associated Factors Among Newly Reported HIV/AIDS Cases Aged ≥50 Years — China, 2022–2024
Abstract
What is already known about this topic?: Late human immunodeficiency virus (HIV) diagnosis remains prevalent among older adults in China; however, recent national-level evidence characterizing its correlates remains limited. What is added by this report?: Using nationwide surveillance data spanning 2022-2024 and employing two complementary analytical approaches, this study identified transmission route and geographic region as primary correlates of late HIV diagnosis. Decision-tree analysis further identified two distinct subgroups in eastern China exhibiting particularly elevated proportions of late diagnosis. What are the implications for public health practice?: These findings provide epidemiological evidence to inform more targeted HIV screening strategies tailored to specific population subgroups, geographic regions, and diagnostic settings.
