Chikungunya Cases Confirmed Along Hong Kong's Tsing Yi Nature Trails

Hong Kong's chikungunya fever (CF) outbreak continues to include both travel-related and locally acquired cases in 2025.

Today, the Hong Kong Centre for Health Protection (CHP) of the Department of Health reported that there have now been 10 local CF cases and 68 cases among travelers.

The CHP wrote on December 7, 2025, that some confirmed CF cases had reportedly been bitten by mosquitoes while hiking along the Tsing Yi Nature Trails, a higher-risk area.

The CHP continued to urge individuals who have recently visited the Tsing Yi North area or hiked along the Tsing Yi Nature Trails to seek medical attention as soon as possible if they develop relevant symptoms and to call the enquiry hotline (Tel: 2125 2373).

The CHP continued to urge the members of the public residing and working at Queen's Road West (near Morrison Street and Hollywood Road) who experienced a fever, rash, or joint pain on or after November 15, 2025, to seek medical advice or contact the CHP immediately.

This area is located northwestern of the inner city and east of Hong Kong Disneyland.

CHP officers continued to reach out to individuals in the locations above, reminding them to be aware of relevant symptoms and to maintain good household hygiene.

To alert international travelers to at-risk areas, the U.S. CDC issued Travel Health Notices in 2025.

As of December 5, 2025, the CDC added Bangladesh and Sri Lanka to the Level 2 notice list.

In the Region of the Americas, over 289,000 CF cases and 141 related fatalities have been reported this year. The majority of these cases have been confirmed in Bolivia, Brazil, and Cuba.

The CDC writes 'You can protect yourself by preventing mosquito bites, which includes using insect repellent. Vaccination is recommended for travelers visiting any area with a CF outbreak in 2025.'

In the United States, chikungunya vaccination services are offered at travel clinics and pharmacies.
