In a follow-up on the situation with locally acquired dengue fever cases in Hong Kong, The Centre for Health Protection (CHP) has reported an additional three local cases of dengue fever, bringing the total to seven.
All three of the new cases tested positive for dengue virus serotype 1 upon laboratory testing.
“The CHP is highly concerned about the recent seven local cases confirmed within a short period of time and has enhanced surveillance through various platforms. Tracing of source of infection is in full swing. We are also working closely with the Food and Environmental Hygiene Department (FEHD) to prevent the spread of infection,” a spokesman for the CHP said.
“We are working closely with the FEHD to assess and prevent possible spread of infection. The FEHD’s vector investigations, surveillance and control are ongoing. The Leisure and Cultural Services Department and Home Affairs Department have also been informed for follow-up. Epidemiological investigations are ongoing,” the spokesman said.
In the rainy season, the public should take heed of the following advice on mosquito control:
- Thoroughly check all gully traps, roof gutters, surface channels and drains to prevent blockage;
- Scrub and clean drains and surface channels with an alkaline detergent compound at least once a week to remove any deposited mosquito eggs;
- Properly dispose of refuse, such as soft drink cans, empty bottles and boxes, in covered litter containers;
- Completely change the water of flowers and plants at least once a week. The use of saucers should be avoided if possible;
- Level irregular ground surfaces before the rainy season;
- Avoid staying in shrubby areas; and
- Take personal protective measures such as wearing light-coloured long-sleeved clothes and trousers and apply insect repellent containing DEET to clothing or uncovered areas of the body when doing outdoor activities.
