New Chikungunya Case Linked to Tsing Yi Nature Trails; Area Closed for Mosquito Control Efforts

DH recorded another local case of chikungunya fever involving Tsing Yi Nature Trails and advises public not to visit the area

The Centre for Health Protection (CHP) of the Department of Health announced that, as of 5pm today (December 10), the CHP has recorded one new local case of chikungunya fever (CF), involving a patient who visited the Tsing Yi Nature Trails during the incubation period. The Tsing Yi Nature Trails is currently closed until further notice. The relevant government departments are conducting large-scale mosquito control and prevention efforts along the trails. To avoid exposure to chemicals or interfering the mosquito control operations, members of the public should not enter the area.

Latest case information

------------------------------

The case involves a 40-year-old male living in Tuen Mun District. A preliminary investigation revealed that he developed joint pain and a fever on December 4 and 5 respectively, followed by rash on December 7. He attended the Accident and Emergency Department of Tuen Mun Hospital yesterday (December 9) and was admitted for treatment in a mosquito-free environment and is now in stable condition. His blood sample tested positive for chikungunya virus upon laboratory testing.

The patient had no travel history during the incubation period. The case is classified as local. He hiked along the Tsing Yi Nature Trails with 11 persons on November 30, and reportedly suffered mosquitoe bites there. Other than that, the CHP found no overlap between his activities during the incubation period and the locations visited by earlier confirmed cases. The CHP considered that the patient likely contracted the infection while hiking near Tsing Yi Nature Trails on that day, and that there is an epidemiological linkage between this case and the recent local cases in Tsing Yi. His household contact and the 11 hiking companions are currently asymptomatic. The CHP has implemented prevention and control measures according to epidemiological investigations and risk assessment, including providing medical surveillance and health advice to the household contacts concerned. If necessary, the CHP will arrange for laboratory testing. The epidemiological investigation is ongoing.

Hong Kong has recorded a total of 79 confirmed CF cases this year. Among them, 11 were local cases, and the rest were imported cases.

Government's comprehensive follow-up actions

-----------------------------------------------------------

Regarding some local cases of CF who visited the Tsing Yi Nature Trails or the surrounding area, the CHP held an interdepartmental meeting with representatives from the Food and Environmental Hygiene Department (FEHD), the Home Affairs Department, the Drainage Services Department (DSD), the Lands Department, and the Civil Engineering and Development Department (CEDD) on December 8, to further confirm measures to strengthen mosquito prevention and control in the vicinity of the Tsing Yi Nature Trails.

The CHP continues to urge individuals not to visit the Tsing Yi Nature Trails. Individuals who have recently 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 yesterday issued another letter to all doctors and hospitals in Hong Kong, urging them to closely monitor whether their patients present with compatible symptoms and arrange blood tests for those concerned. The CHP's Public Health Laboratory Services Branch will provide free testing services.

Specifically targeting confirmed cases who visited the Tsing Yi Nature Trails or the surrounding area, the FEHD has been continuously conducting intensive fogging operations to eliminate adult mosquitoes along the hiking trails. At suitable locations, large ultra-low volume foggers have been deployed, and robot dog is being put on trial to enhance operational effectiveness. The FEHD has also set up new mosquito trapping devices, cleared discarded containers and garbage that could bring stagnant water, and applied larvicide oil or larvicides in areas with stagnant water that cannot be removed immediately. The FEHD has been collaborating with Kwai Tsing District Office, Lands Department and Drainage Services Department to strengthen efforts in eliminating potential mosquito breeding sites along the Tsing Yi Nature Trails. Pamphlets have been distributed to hikers in the area, urging citizens to be vigilant against mosquito infestations and take personal protective measures. The FEHD also held meetings of the interdepartmental task forces on anti-mosquito work across districts, to discuss the latest developments regarding the situation and plan accordingly to co-ordinate relevant departments and stakeholders in strengthening mosquito prevention and control measures in areas under their purview.

Furthermore, the FEHD and relevant departments have comprehensively enhanced the mosquito control operations in Hong Kong since July this year, and this has continued. Among these, the FEHD has conducted vector investigations and targeted mosquito control operations against the imported and local cases. In light of the local cases, the FEHD has immediately conducted follow-up actions, including:

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 abovementioned measures will be continued. Furthermore, the Government will further enhance the mosquito control efforts in addition to the existing measures.

Members of the public should use DEET-containing insect repellents or other effective active ingredients properly to 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 empty cans and lunch boxes. The FEHD also advises members of the public and property management agencies 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.
