Dengue 登革熱

What is Dengue? 什麼是登革熱?

  • Dengue is an acute infection caused by the dengue virus Flavivirus. Clinically it can manifest as dengue fever or dengue haemorrhagic fever (DF/DHF).
  • 登革熱病是由登革熱病毒引致的急性傳染病,患者的臨床情況可分為登革熱及登革出血熱。
  • Oviposition trap (Ovitrap) index is a marker for assessing mosquito growth using a simple device placed in the outdoor environment. This in turn supports the evaluation of dengue risk in the human population.
  • 誘蚊指數是以簡單儀器放置戶外,藉以評估伊蚊生長的況,所得指標,用以反映人群感染登革熱的危機。

How does it spread? 如何傳播?

  • Dengue is spread through the bite of several species of the Aedes mosquito which carries the dengue virus. In Hong Kong and Macao, the responsible vector is Aedes Albopictus. Aedes aegypti is the most important vector worldwide. Both types of mosquitoes are found in Taiwan.
  • 登革熱是經被帶有病毒的伊蚊叮後而傳播的傳染病。在香港,白紋伊蚊是常見的傳播媒介,而全球最重要的則是埃及伊蚊。台灣是兩種伊蚊並存。

Vaccine? Prevention? 如何預防?

  • Currently there is no promising vaccine to protect from dengue virus. The best measure is to minimise the breeding grounds of the Aedes mosquitoes by for example sealing up puddles of stagnant water, and avoiding mosquito bites.
  • 目前仍未有有效防登革熱病毒感染的疫苗。預防措施的重點首是減少伊蚊繁殖的地方,包括清除積水防止蚊子滋生,以及避免被蚊子叮咬。
