Summary
Hong Kong recorded 171 new cases of human immunodeficiency virus (HIV) infection and 28 new cases of acquired immunodeficiency syndrome (AIDS) in the first half of 2026, as health authorities expressed concern over a persistently high proportion of late presenters . The Centre for Health Protection (CHP) reported that the new HIV cases involved 143 men and 28 women aged between 19 and 80, with about 70 percent aged 20 to 49 and nearly 30 percent aged 50 or above . Sexual contact accounted for 99 percent of the cases with a reported route of transmission, including 94 cases through homosexual or bisexual contact and 46 through heterosexual contact . While annual new HIV cases have declined for 10 consecutive years, the CHP noted that the proportion of late presenters among newly diagnosed individuals has remained high at around 50 percent . Bonnie Wong Chun-kwan, Consultant (Special Preventive Programme) of the Department of Health, warned that some individuals mistakenly believe they are at low risk of infection, leading to delayed testing and treatment .
Key Points
- Hong Kong recorded 171 new HIV infections and 28 new AIDS cases in the first six months of 2026, involving 143 men and 28 women aged 19 to 80
- Sexual contact was the primary transmission route, accounting for 99 percent of cases, with 94 from homosexual or bisexual contact and 46 from heterosexual contact
- The proportion of late presenters remains at about 50 percent, with nearly 80 percent of these individuals having never been tested for HIV before diagnosis
- Late presentation rates are higher among general-risk populations at 60 to 70 percent compared to 40 to 50 percent among higher-risk groups like sex workers and men who have sex with men
- The Department of Health is urging all sexually active individuals, regardless of age or sexual orientation, to undergo HIV testing at least once
Why It Matters
Late diagnosis of HIV significantly increases the risk of opportunistic infections, cancer, and death, while an active viral load also heightens the risk of community transmission . The high proportion of late presenters, particularly among the general population who often perceive themselves as low-risk, underscores the need for broader public health messaging to normalize HIV testing as a routine part of sexual health care .
