The Food and Environmental Hygiene Department (FEHD) has urged the public to step up anti-mosquito measures and stay alert to the risk of mosquito-transmitted diseases as the current rainy season and humid weather are most favourable for mosquito breeding.
An FEHD spokesman said today (September 17) that the monthly average ovitrap index for August had dropped slightly to 10.2% from 13% in July. The ovitrap indices reflect the prevalence of Aedes albopictus, a mosquito vector for dengue fever transmission.
The inter-departmental anti-mosquito response mechanism has been activated in the two districts which recorded readings at or above the alert zone of 20%, namely Lek Yuen (23.6%) and Chai Wan West (20%).
"The departments concerned have stepped up inspection and measures to enhance environmental hygiene conditions in areas under their ambits. The aim is to eliminate existing and potential mosquito-breeding grounds in addition to the regular weekly programme," the spokesman said.
"The FEHD will also closely monitor the situation in other areas, and strengthen control measures whenever necessary."
As for port areas, the average ovitrap index stayed at 0.8% as in July.
Aedes albopictus can breed in very 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.
"After rain, they should remove water from balconies, rooftops and courtyards immediately," he added.
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 ).
