CHP announces local HIV/AIDS situation for first half of 2025 26/08/2025

The Centre for Health Protection (CHP) of the Department of Health (DH) announced today (August 26) that a total of 180 new cases of Human Immunodeficiency Virus (HIV) infection and 47 new cases of Acquired Immunodeficiency Syndrome (AIDS) were reported in the first half of 2025 in Hong Kong. In response to the persistently high proportion of late presentation, the DH encouraged the public to undergo HIV antibody testing and to use condoms regularly and correctly to minimise the risk of HIV infection.

The 180 new HIV cases involve 140 men and 40 women aged between 20 and 75. Investigations revealed that over 95 per cent of the cases were infected through sexual contact, of which more than half (57 per cent) were acquired via homosexual or bisexual contact, and the rest were acquired via heterosexual contact. The number of new cases of HIV infection in Hong Kong has declined for the ninth consecutive year. Compared to the same period last year (185 cases), the number of new HIV cases has slightly decreased by 3 per cent. The cumulative total of locally reported HIV infections since 1984 is 12 583.

The new AIDS cases include 33 men and 14 women. Since 1985, a cumulative total of 2 604 AIDS cases has been reported in Hong Kong. The most common AIDS-defining illness was Pneumocystis pneumonia.
