The Food and Environmental Hygiene Department (FEHD) reminded the public to stay alert to the potential hazards of mosquito-transmitted diseases and maintain proper preventive measures with the approach of the rainy season.
An FEHD spokesman said today (March 24) that the monthly average ovitrap index for February rose slightly from zero in January to 0.1%. The ovitrap indices reflect the prevalence of Aedes albopictus, a mosquito vector for dengue fever transmission.
Among the 44 areas surveyed last month, a positive ovitrap indice was only recorded in Cheung Sha Wan at 1.8%.
As for port areas, the average ovitrap index dropped to zero from 0.1% in January.
"Despite the low index levels recorded in February, preventive measures should not be relaxed as mosquito eggs start to hatch in the coming rainy season. The humid and warm weather is also highly favourable to the proliferation of mosquitoes," the spokesman said.
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.
Moreover, people travelling during the Easter holidays next month to areas where mosquito-borne diseases prevail are advised to take the following precautionary measures:
* Wear light-coloured, long-sleeved clothes and trousers;
* Use insect repellents over exposed parts of the body when staying outdoors; and
* Use mosquito screens or nets when the room is not air-conditioned.
Travellers returning from these places should seek medical advice if they have symptoms such as fever, severe headache or muscle and joint pain. They should also inform their doctor of their travel history.
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.
