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.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
