Hong Kong Reports New Imported Chikungunya Fever Case; Public Urged to Enhance Mosquito Control Measures

Update on chikungunya fever

The Centre for Health Protection (CHP) of the Department of Health (DH) announced that as of 5pm today (August 12), one new imported case of chikungunya fever (CF) had been recorded. The CHP reminded members of the public to maintain strict environmental hygiene and to take mosquito control and personal protective measures both locally and when travelling outside Hong Kong. Those who suspect they may be infected with CF should seek medical advice promptly and avoid self-testing, which can lead to delays in diagnosis and treatment.

Latest case information

The new case involves a 31-year-old male with good past health who lives in Kwai Tsing District. Preliminary investigations revealed that he travelled to Foshan in Guangdong Province from August 1 to 3. He could not confirm whether he had a history of mosquito bites. Upon returning to Hong Kong, he developed a fever, rash and joint pain on August 8. He travelled to Shenzhenon August 9 and attended a hospital there the next day. He was not admitted and returned to Hong Kong on the same day. He attended the Accident and Emergency Department of Yan Chai Hospital yesterday (August 11) and was admitted for treatment in a mosquito-free environment. He is currently in stable condition. His blood sample tested positive for the CF virus upon laboratory testing.

Since the patient stayed in Foshan during the incubation period, the CHP considered that he was infected during travel, and the case was classified as imported. The patient has no travel collaterals and his household contacts are currently asymptomatic and are under medical surveillance. The CHP will continue its epidemiological investigation and has reported the case to the health authorities of Guangdong.

Hong Kong has recorded a total of six confirmed CF cases this year, all of which are imported cases, as well as one probable case. From 2016 to 2019, Hong Kong recorded between one and 11 imported cases annually.

Continuously strengthening prevention and control

"According to information from the Guangdong Provincial Disease Control and Prevention Administration, in the past week (August 3 to 9), there were 1 387 new CF cases in Guangdong, a significant decrease compared to the previous two weeks, which reported 2 892 cases (July 27 to August 2) and 2 940 cases (July 20 to 26) respectively. All the cases were mild, with no severe or fatal cases reported. However, we must remain vigilant and continue to adopt a multipronged approach to prevent local transmission," said the Controller of the CHP, Dr Edwin Tsui.

The CHP's Port Health Division continues to step up inspections at boundary control points and to 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 screening for inbound travellers, conduct health assessments for travellers with fever or related symptoms, and refer them to hospitals for follow up when necessary.

To raise the awareness among the elderly about preventing CF, the Visiting Health Teams under the Elderly Health Service of the DH have been advising the elderly on CF prevention and travel health at health talks conducted at District Elderly Community Centres and Neighbourhood Elderly Centres. They have also reminded residential care homes for the elderly to enhance mosquito control measures. The DH's Maternal and Child Health Centres, Student Health Service Centres and Special Assessment Centres also advise pregnant women, infant carers and students on symptoms and preventive measures of CF.

To strengthen support for ethnic minority communities, essential information on CF has also been translated into 10 ethnic minority languages (including Hindi, Nepali, Urdu, Thai, Bahasa Indonesia, Tagalog, Vietnamese, Punjabi, Sinhala and Bengali) and uploaded to the CHPwebsite.

Dr Tsui reminded members of the public, currently, there are no rapid test products on the market that have been certified by international health authorities for public use in self-testing for CF. They should promptly seek medical advice if they suspect they are infected with CF and not to conduct testing on their own as this may delay proper clinical treatment. He also urged the public not to self-medicate, particularly with aspirin or non-steroidal anti-inflammatory drugs (such as ibuprofen), as these drugs may cause serious side effects, for example, increasing the risk of haemorrhage. In general, children should not take medications containing aspirin to relieve fever or other symptoms because it may lead to "Reye's syndrome", a serious and potentially fatal complication.

He also added that members of the public should adopt precautions in the rainy season against mosquito-borne diseases. Proper use of DEET-containing insect repellents or other effective active ingredients can effectively 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 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 andpicaridin. When using any insect repellent, the public should follow the usage instructions and precautions on the product label.

In addition, the Food and Environmental Hygiene Department (FEHD) 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.

The public should call 1823 in case of mosquito problems and may visit the following pages for more information: the CF page of theCHPand theTravel Health Service, the latestTravel Health News,tips for using insect repellents, and the CHPFacebook Page,Instagram AccountandYouTube Channel, and also theMosquito Prevention and Control dedicated pageof the FEHD.

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.
