Update on chikungunya fever

The Centre for Health Protection (CHP) of the Department of Health announced that as of 5pm today (October 12), one new case of chikungunya fever (CF) had been recorded.

Latest case information

The case involves a 65-year-old female living in Yau Tsim Mong District. Preliminary investigation revealed that she visited Guangzhou in Guangdong between October 5 and 10. She developed joint pain on October 10, and a fever and rash on the following day. She then sought medical attention at the Accident and Emergency Department of Caritas Medical Centre and was admitted for treatment in a mosquito-free environment on October 11. She is now in stable condition. Her blood sample tested positive for the CF virus upon laboratory testing by the Hospital Authority. She has no household contact.

Since the patient stayed in Guangdong Province during her incubation period, the CHP considered that she was infected during travel. The case was classified as imported. The CHP's epidemiological investigation is ongoing, and it has reported the case to the health authority of Guangdong Province.

Latest surveillance data

So far this year, Hong Kong has recorded a total of 32 confirmed CF cases. All are imported cases. From 2016 to 2019, Hong Kong recorded between one and 11 imported cases annually.

Since the beginning of 2025, and as of September 30, a total of 445 271 suspected and confirmed CF cases and 155 CF-related deaths have been reported in 40 countries/territories. Cases have been reported in the Americas, Africa, Asia, and Europe. CF outbreaks currently occur in many countries worldwide. Members of the public should check the situation of the destinations before travelling abroad.

Continuously strengthening prevention and control

The Food and Environmental Hygiene Department (FEHD) continues to conduct vector investigations and targeted mosquito control operations, and intensify mosquito prevention and control measures at the residences of recently confirmed patients, as well as at locations visited after the onset of symptoms. These measures include:

carrying out intensive fogging in scrubby areas within a 250-metre radius of the relevant locations to kill adult mosquitoes;

carrying out inspections of the locations, removing stagnant water, applying insecticides and disposing of abandoned water containers every week with a view to preventing mosquito breeding; and

enhancing public education efforts through organising health talks, setting up mobile education stations, and distributing publicity leaflets.

The CHP urged schools to follow the FEHD's anti-mosquito guidelines to strengthen efforts to clear stagnant water on school premises and eliminate mosquito breeding sites. It is also imperative to remind staff members and students to consistently implement mosquito prevention and personal protective measures to guard against the spread of mosquito-borne diseases within school premises.

Additionally, the CHP's Port Health Division continues to step up inspections at boundary control points and remind cross-boundary public transport operators and other relevant parties to ensure good environmental hygiene and effective implementation of anti-mosquito measures. Furthermore, staff members of the Port Health Division distribute leaflets to travellers, conduct temperature screenings for inbound travellers, conduct health assessments for travellers with fever or related symptoms and refer them to hospitals for follow-ups when necessary.

Proper use of DEET-containing insect repellents or other effective active ingredients can prevent mosquito bites, but the following precautions should be taken when using them:

read the label instructions carefully first;

apply right before entering an area with a risk of mosquito bites;

apply on exposed skin and clothing;

use DEET of up to 30 per cent for pregnant women and up to 10 per cent for children (For children who travel to countries or areas where mosquito-borne diseases are endemic or epidemic and where exposure is likely, those aged 2 months or above can use DEET-containing insect repellents with a DEET concentration of up to 30 per cent);

apply sunscreen first, then insect repellent;

reapply only when needed and follow the instructions; and

in addition to DEET, there are other insect repellents available on the market containing different active ingredients, such as IR3535 and picaridin. When using any insect repellent, the public should follow the usage instructions and precautions on the product label.

The FEHD also appeals to members of the public to continue to stay alert and work together to carry out mosquito prevention and control measures early, including inspecting their homes and surroundings to remove potential breeding grounds, changing water in vases and scrubbing their inner surfaces, removing water in saucers under potted plants at least once a week, and properly disposing of containers such as soft drink cans and lunch boxes. The FEHD also advises members of the public and estate management bodies to keep drains free of blockage and level all defective ground surfaces to prevent the accumulation of water. They should also scrub all drains and surface sewers with an alkaline detergent at least once a week to remove any mosquito eggs.
