1 Dengue fever is transmitted to humans through bites from infected female Aedes mosquitoes – a common species that can also spread Zika.

2 Severe dengue fever is potentially fatal. Symptoms begin three to 14 days after infection and can include fever, headache, vomiting, muscle and joint paint, and a rash.

3 There is no dengue vaccine currently available in Hong Kong, so it’s important to avoid mosquitoes both locally and when travelling. Travellers need to take preventive measures like wearing loose, light-coloured, long-sleeved tops and trousers, and using Deet-containing insect repellent on exposed parts of the body and clothing.

Third case of Dengue fever found in Hong Kong: even more reason to avoid mosquitoes

4 Dengue is common in more than 110 countries and infects millions of people every year, with about 20,000 deaths.The disease was once only found in Southeast Asia, but has spread to southern China, the US and countries in the Pacific Ocean.

5 After returning from dengue endemic areas, people should continue to apply insect repellent for 14 days, according to the Centre for Health Protection. Anyone feeling unwell after returning from a trip should seek medical advice as soon as possible and provide travel details to their doctor. The public can also report mosquito problems to government departments via the hotline 2125 2266.
