Public urged to step up anti-mosquito efforts in rainy season

Despite the zero ovitrap indices recorded last month, the Food and Environmental Hygiene Department (FEHD) today (April 29) 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.

"The monthly average ovitrap index for March dropped to 0%, from 0.1% in February. As for port areas, the index 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 a 10-week Anti-mosquito Campaign for this year was launched on Tuesday (April 26).

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 territory.

Aedes albopictus breeds in small water bodies. The spokesman advised the public and estate management bodies to scrub all drains and surface sewers, and limewash them with 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.

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.

The ovitrap indices and information on anti-mosquito measures under the Anti-mosquito Weekly Inspection Programme are available on the department's website, www.fehd.gov.hk.
