The Centre for Health Protection (CHP) of the Department of Health is recently investigating an imported co-infection case of Zika virus and dengue fever (DF), and urged the public to maintain strict environmental hygiene as well as to adopt strict anti-mosquito measures during travel. Please click here for details.

Zika virus and dengue virus are primarily transmitted to humans through the bite of an infected Aedes mosquito. To reduce the risk of infections spread by mosquitoes, apart from general measures, travellers returning from affected areas should apply insect repellent for 14 days (DF) or at least 21 days (Zika Virus Infection) upon arrival in Hong Kong. If feeling unwell, seek medical advice promptly and provide travel details to the doctor.

The public should call 1823 in case of mosquito problems and may visit the following pages for more information: the DF page of the CHP and the Travel Health Service, the Zika pages of the CHP and the Travel Health Service, the latest Travel Health News, tips for using insect repellents, and the CHP Facebook Page and YouTube Channel.
