親愛的同事及同學們：

近日天氣持續不穩，連日下雨造成校園環境積水，容易孳生蚊蟲。為降低蚊媒傳播疾病的風險，請參閱以下衛生局發出的預防登革熱及基孔肯雅熱資訊及預防措施。

清除積水，防止蚊蟲孳生

  • 每周至少檢查周圍環境一次，確保積水有定期清理。
  • 水種植鮮花、植物的容器至少每星期換水及沖洗根部一次，並徹底刷洗花瓶容器；或以海綿等填塞花瓶口，以阻隔蚊蟲進入水中產卵。
  • 避免使用花盆底盤。
  • 倒置積水容器。
  • 由於白紋伊蚊可在範圍細小的積水產卵和孳生，垃圾應包好並妥善棄置在有蓋的垃圾桶內。
  • 檢查和修復水管滲漏情況，並保持渠道暢通。

減少蚊子進入室內

  • 如有需要，可使用防蚊滅蚊設備，例如：紗窗、滅蚊燈或蚊香等，降低室內被叮咬的風險。

採取個人防護措施

  • 避免到樹蔭草叢等陰暗處逗留，以免被白紋伊蚊叮咬。
  • 外出或外遊時，應穿著淺色長袖衫及長褲，並在皮膚外露的部分搽上驅蚊劑。
  • 外遊時，選擇在有空調或有防蚊設施的地方休息。


如有發熱、出疹或關節痛症狀，必須停止上班或上課，前往就醫及加強採取以上防護措施，並進行14天的自我健康管理。

若有疑問，可致電衛生局傳染病熱線2870 0800，或可瀏覽衛生局的預防登革熱及基孔肯雅熱專頁。

Dear colleagues and students,

The weather remains unstable recently and continuous rain causes stagnant water on campus, making it easy for mosquitoes to breed. In order to reduce the risk of mosquito-borne diseases, the Health Bureau has published the below information and measures for the prevention of Dengue fever and Chikungunya fever for your reference.

Eliminate stagnant water to prevent mosquito breeding

  • Check the surrounding environment at least once per week to ensure stagnant water is regularly removed.
  • For hydroponic flowers and plants, replace the water, rinse the roots and scrub the vases thoroughly at least once per week, or close the vase mouth with sponges to prevent mosquitos from laying eggs in the water.
  • Avoid using flowerpot saucers.
  • Containers prone to stagnant water should be placed upside down.
  • Since Aedes Albopictus can lay eggs in a small volume of stagnant water, trash should be sealed and disposed of properly in trash bins with lids.
  • Check the waterpipes for leakage and carry out repairs if any; drains should be kept unclogged.

Remove mosquitoes from indoor environments

  • Use mosquito repellent equipment if available, such as screen windows, mosquito killer lamps and mosquito coils, to lower the risk of getting mosquito bites indoors.

Take personal preventive measures

  • Avoid staying in dark places such as shaded or vegetated areas to prevent being bitten by Aedes albopictus.
  • When going out or travelling, wear light-coloured, long-sleeved clothes, and apply mosquito repellent on exposed body parts.
  • When travelling, take a rest in places with air conditioners or anti-mosquito facilities.


If you have symptoms of fever, rash, or joint pain, you should not go to work or classes. Seek medical attention and strengthen the above protective measures, and conduct self-health management for 14 days.

For enquires, kindly contact the Health Bureau hotline 2870 0800 or visit the Dengue Fever and Chikungunya Fever Prevention website  issued by the Health Bureau.
