The Centre for Health Protection (CHP) of the Department of Health announced that as of 5pm today (November 8), no new cases of chikungunya fever (CF) had been recorded. 
     
     Hong Kong has recorded a total of 59 confirmed CF cases this year. Among them, three were local cases and the rest were imported cases.
          
Government's comprehensive follow-up actions
--------------------------------------------------------------

     In light of a locally acquired case recorded in Kwai Tsing District earlier this week, the CHP conducted a risk assessment and collaborated with relevant District Services & Community Care Teams to distribute leaflets on CF prevention to over 10 000 households in Mount Haven and the surrounding areas, Kwai Chung Plaza, Shun Tak Centre in Sheung Wan and the vicinity to remind residents to monitor for relevant symptoms and maintain good environmental hygiene at home.
       
     From November 3 to 5pm today, the CHP has conducted assessments for over 13 000 individuals residing or working in higher-risk districts through health consultation booths, along with its inquiry hotline, door-to-door visits and questionnaire surveys conducted in the districts concerned. The CHP has arranged blood tests for a total of 14 persons who had mild symptoms and all were tested negative. No new symptomatic persons have been identified in the past one day. The health consultation booths located at Cheung Hang Community Hall in Tsing Yi and Kwai Fong Estate (near Kwai Ming House) will continue to provide assessments for the citizens in the districts daily from 9am to 1pm. The previously established inquiry hotline (2125 2373) will also continue to operate daily from 9am to 6pm.
  
     The Food and Environmental Hygiene Department (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 case, 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.
 
Preventive measures taken by the public
----------------------------------------------
 
      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 the CHP and the Travel Health Service, the latest Travel Health News, tips for using insect repellents, and the CHP Facebook Page, Instagram Account and YouTube Channel, and also the Mosquito Prevention and Control dedicated page of the FEHD.
