Summary
The Centre for Health Protection (CHP) reported a notable surge in monkeypox cases in Hong Kong, with 29 cumulative cases recorded this year as of October 5, 2026. Twenty of these cases emerged since August, with 15 classified as locally acquired and 5 as imported infections. Dr. Au Ka-wing (歐家榮), Head of the Communicable Disease Branch at the CHP, stated on a radio programme that epidemiological investigations have not identified specific connections between cases, such as shared venues or activities, suggesting transmission is spreading within a closed network. Sixty percent of infected individuals reported finding casual sexual partners through dating applications, leaving many unable to provide contact details for their partners. Genetic sequencing of virus samples from the 20 recent cases has revealed identical gene sequences in some instances, confirming shared transmission sources and the existence of multiple transmission chains.
Key Points
- Hong Kong has recorded 29 monkeypox cases in 2026, surpassing the combined total of the previous two years, with 22 local and 7 imported cases
- Twenty cases emerged since August 2026, with 15 locally acquired and 5 imported; all patients are men who have sex with men
- Approximately 60% of those infected used dating applications to find sexual partners, severely limiting contact tracing efforts
- All patients reported high-risk sexual behaviours during the incubation period, including sex with strangers, multiple partners, or without condoms
- The CHP has strengthened monkeypox prevention promotions on social media platforms and dating apps, while adding vaccine centres at its headquarters
Why It Matters
The surge in monkeypox cases highlights the challenges public health authorities face when infections spread within close-knit communities that rely on anonymous social networks for sexual encounters. The CHP's inability to trace contacts effectively means infected individuals may continue spreading the virus unknowingly, underscoring the importance of the centre's appeal for people to retain their sexual partners' contact information. With Hong Kong's monkeypox cases already exceeding the total of the past two years combined, health officials emphasise that vaccination and responsible contact retention remain critical tools for containing the outbreak.
