Three New Chikungunya Fever Cases Reported in Hong Kong, All Linked to Travel Abroad

Update on chikungunya fever

The Centre for Health Protection (CHP) of the Department of Health announced that as of 5pm today (October 15), three new cases of chikungunya fever (CF) had been recorded.

　

Latest cases information

The first case involves a 77-year-old male living in Eastern District. A preliminary investigation revealed that he visited Guangzhou in Guangdong between September 30 and October 13. He developed a fever and joint pain on October 13, and rash yesterday (October 14). He then sought medical attention at a private hospital. His household contact, who travelled with him to Guangzhou, is currently asymptomatic and under medical surveillance.

The second case involves a 34-year-old male living on Lantau Island. A preliminary investigation revealed that he travelled alone to Indonesia between October 2 and 4. He also travelled to Macao between October 6 and 7, and Shenzhen and Dongguan in Guangdong between October 10 and 12. He developed a fever, joint pain and rash on October 13. He sought medical attention at the Accident and Emergency Department of North Lantau Hospital yesterday. He has two household contacts. His travel companions included his relatives (including one household contact) and colleagues. All are currently asymptomatic and under medical surveillance.

The third case involves a 72-year-old male living alone in Central and Western District. A preliminary investigation revealed that he visited Foshan in Guangdong alone between October 4 and 12. He developed a fever and joint pain on October 13 and sought medical attention at the Accident and Emergency Department of Queen Mary Hospital yesterday.

All three males were admitted to the hospitals for treatment in a mosquito-free environment and are in stable condition. Their blood samples tested positive for the CF virus upon laboratory testing. Since they visited areas affected by CF during their incubation periods, the CHP considered that they were infected during travel. The cases were classified as imported. The CHP's epidemiological investigations are ongoing, and it has reported the cases to relevant health authorities.

Latest surveillance data

So far this year, Hong Kong has recorded a total of 38 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.

Secretary for Health attends 20th Joint Meeting of Senior Health Officials of Mainland, Hong Kong and Macao in Macao

The Secretary for Health, Professor Lo Chung-mau, led a delegation to attend the 20th Joint Meeting of Senior Health Officials of the Mainland, Hong Kong and Macao hosted by the Macao Special Administrative Region (SAR) Government in Macao today (January 15).

The annual Joint Meeting has long been a platform for senior medical and health officials as well as experts from the Mainland, Hong Kong and Macao to exchange views and share experiences on present-day medical and public health issues, as well as to promote healthcare service development. The Joint Meeting is hosted by the Mainland, Hong Kong and Macao in rotation.

The Minister of the National Health Commission, Mr Lei Haichao, and the Secretary for Social Affairs and Culture of the Macao SAR Government, Ms O Lam, led senior health officials from the Mainland and the Macao SAR Government respectively to participate in the meeting. Members of the delegations of the three places today engaged in sharing and discussions over three major topics, namely nurturing interdisciplinary and composite talent in clinical management, disease prevention and control, and medical administration; strengthening primary healthcare services to safeguard community health, and the application of smart healthcare in the health sector.

Professor Lo said, "The Recommendations of the Communist Party of China (CPC) Central Committee for Formulating the 15th Five-Year Plan for National Economic and Social Development, adopted at the Fourth Plenary Session of the 20th CPC Central Committee, features the term 'reform' 23 times, unequivocally underscoring the nation's steadfast commitment to deepening reforms. Hong Kong has consistently been playing an active role in the course of the country's reform and opening up. Serving as a 'super connector' between the Mainland and the world, Hong Kong also functions as an indispensable 'super value-adder', facilitating the nation's effort in going global while attracting foreign investment to the Mainland market.

"The Chief Executive of the Hong Kong Special Administrative Region (HKSAR) has consistently emphasised in the Policy Addresses of the past three years the HKSAR Government's full commitment to developing Hong Kong into an international health and medical innovation hub, and to vigorously foster new quality productive forces. To achieve this significant objective, the HKSAR Government is actively advancing various initiatives, including the setting up of the Hong Kong Centre for Medical Products Regulation within this year, with a view to establishing the Centre as an internationally recognised regulatory authority for medical products as soon as possible; the official launch of the Greater Bay Area (GBA) Clinical Trial Collaboration Platform last month, enabling pharmaceutical companies to conduct trials simultaneously in Hong Kong and Shenzhen; as well as the commissioning of the Real-World Study and Application Centre to promote the standardisation of clinical data across the GBA."

The Chief Executive of the Hospital Authority (HA), Dr Libby Lee, and the Director of Cluster Services of the HA, Dr Wong Yiu-chung, moderated a discussion and gave a presentation on the application of smart healthcare in the health sector respectively. Meanwhile, the acting Deputy Director of Health, Dr Jackie Leung, and the Commissioner for Primary Healthcare, Dr Pang Fei-chau, delivered presentations on the topic of nurturing interdisciplinary and composite talent in clinical management, disease prevention and control, and medical administration; as well as on the topic of strengthening primary healthcare services to safeguard community health respectively.

Members of the HKSAR Government delegation included the Chairman of the HA, Mr Henry Fan, and the Director of Health, Dr Ronald Lam, who concluded the discussion at the meeting.

Professor Lo will return to Hong Kong in the evening. During his absence, the Under Secretary for Health, Dr Cecilia Fan, is the Acting Secretary for Health.
