CHP announces no new confirmed chikungunya fever infection cases today (with photos)
************************************************************************************
     The Centre for Health Protection (CHP) of the Department of Health (DH) today (August 4) said that no new confirmed chikungunya fever (CF) infection cases had been recorded as at 5pm today. The CHP will continue to strengthen its surveillance work in view of the recent CF case. Members of the public are advised to maintain strict environmental hygiene, mosquito control and personal protective measures both locally and when travelling outside Hong Kong. Avoiding mosquito bites and eliminating mosquito breeding sites are effective ways to prevent CF.

     A total of one CF case has been recorded in Hong Kong this year, which is an imported case. From 2016 to 2019, between one and 11 CF cases were recorded in Hong Kong each year, all of which were imported cases.

     The CHP's Port Health Division has stepped up publicity and education efforts regarding CF at boundary control points, conducting more frequent inspections to ensure good environmental hygiene and effective implementation of anti-mosquito measures. Staff members today conducted inspection at MTR Lok Ma Chau Station and its vicinity with staff members of the MTR Corporation Limited and recommended anti-mosquito measures. In addition, staff members also conduct temperature screening for inbound travellers. Any travellers with fever or related symptoms will be assessed for their health condition and referred to hospitals for follow-up when necessary. The CHP also maintains close liaison with relevant stakeholders, such as airlines and the travel industry, to provide the latest disease information and health advice in a timely manner.

     The Head of the Communicable Disease Branch of the CHP, Dr Albert Au, reminded members of the public that if they return from areas affected by mosquito-borne diseases, they should apply insect repellent for 14 days upon arrival in Hong Kong. Members of the public should closely observe their personal health condition, in particular symptoms such as fever, joint pain and rash. If they feel unwell, they should seek medical advice promptly and provide their travel details to the doctor for clinical diagnosis and arrange appropriate testing based on an individual patient's condition. Members of the public are urged 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.

     The Food and Environmental Hygiene Department (FEHD) has intensified anti-mosquito measures at the residence of the confirmed patient and the locations visited after the onset of illness. The 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 as well as 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 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 latest gravidtrap indices for Aedes albopictus in different survey areas are available on the department website at: www.fehd.gov.hk/english/pestcontrol/dengue_fever/Dengue_Fever_Ovitrap_Index_Update.html#.

     The CHP will collaborate with the FEHD to hold an online live seminar on its Facebook page tomorrow (August 5) from 8pm to 8.30pm, to provide information and health advice on preventing mosquito bites and controlling mosquito breeding, as well as addressing related public enquiries. Members of the public are welcome to attend.

     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 Newstips for using insect repellents, the CHP Facebook PageInstagram Account and YouTube Channel, and also Mosquito Prevention and Control dedicated page of the FEHD.
