Although the ovitrap indices recorded last month stayed at zero, the Food and Environmental Hygiene Department (FEHD) today (April 21) reminded the public to keep up effective measures against mosquito breeding and to stay alert to the risk of mosquito-transmitted diseases with the advent of the rainy season.
"Both the monthly average ovitrap index and the monthly port ovitrap index for March stayed at zero as in February," an FEHD spokesman said.
The ovitrap indices reflect the prevalence of Aedes albopictus, a mosquito vector for dengue fever transmission.
"During this time of the year, when the rainy season is round the corner, the humid and warm weather is conducive to mosquito breeding. Therefore, anti-mosquito measures should not be relaxed," the spokesman said.
In order to heighten public awareness of the potential risk of mosquito-borne diseases, including dengue fever and Japanese encephalitis, the second phase of an Anti-mosquito Campaign, which will last for 10 weeks, will be launched next Monday (April 28).
During the three-phase campaign period, relevant government departments and public bodies will strengthen mosquito prevention and control measures as well as publicity efforts throughout the city.
Aedes albopictus breeds in small water bodies. The spokesman advised the public and estate management bodies to scrub all drains and surface sewers, and to limewash them with an alkaline detergent compound at least once a week to remove any mosquito eggs. They should also keep the drains free from blockage and fill up all depressions to prevent puddles from forming.
People should inspect their homes and surroundings to remove potential breeding grounds, scrub vases and pot plant saucers at least once a week, properly dispose of containers such as soft drink cans and lunch boxes, and drill large holes in unused tyres, he added.
The ovitrap indices and information on anti-mosquito measures under the Anti-mosquito Weekly Inspection Programme are available on the department website: www.fehd.gov.hk.
