FEHD implements multi-pronged mosquito control measures and urges public vigilance against chikungunya fever (with photos)

In response to the recent surge in chikungunya fever cases reported in neighbouring regions and some overseas countries, the Food and Environmental Hygiene Department (FEHD) has stepped up mosquito prevention and control efforts through a multi-pronged approach. The FEHD also appeals to members of the public to strengthen anti-mosquito measures. The FEHD and the Department of Health will meet and collaborate with the stakeholders from the property management sector to enhance mosquito control work.
     
Chikungunya fever is a mosquito-borne disease. To safeguard public health, the FEHD is implementing the following measures:

• Convening meetings of the inter-departmental task forces on anti-mosquito work across districts. Members of the task force include relevant departments and stakeholders. Targeted and sustained mosquito control actions will be carried out at locations with higher mosquito infestation risks, based on the latest Gravidtrap Index for Aedes albopictus；
• Collaborating with departments such as the Housing Department and the Leisure and Cultural Services Department to strengthen inspections in public areas, public housing estates and parks. Upon detection of mosquito breeding grounds, immediate actions will be taken, including conducting fogging operations to eliminate adult mosquitoes, removal of stagnant water and water-holding containers, application of larvicides (e.g. temephos sand granules), and installation of mosquito traps;
• Enhancing inspections at construction sites, works areas and private residences. Enforcement actions will be taken against violations involving mosquito breeding;
• Issuing letters and organising seminars for property management companies and organisations to disseminate the latest information on chikungunya fever and mosquito prevention. The FEHD also invites the Housing Department and property management companies to conduct mosquito control campaigns in housing estates and encourages resident participation;
• Working with the District Offices to assist in mosquito prevention and control at locations with infestation issues, such as "three-nil" buildings; and
• Strengthening public education and publicity through promotional videos, posters and leaflets to remind the public to adopt mosquito control measures. The FEHD will also enhance dissemination of the Area Gravidtrap Index for Aedes albopictus to raise awareness in districts with higher readings.

Public participation is crucial in addition to the government and the trade's efforts. Members of the public are urged to continue joining hands in taking mosquito prevention and control measures at home and other places promptly. The measures include:

• Keep the environment clean by disposing of rubbish properly. Refuse like empty cans and food containers where water can accumulate easily should be disposed of in covered litter containers;
• Clean the saucers under potted plants weekly and prevent water accumulation;
• Change the water in vases and scrub their internal surface every week;
• Keep water-storage containers, such as buckets and basins, tightly covered; and
• Check umbrella stands, umbrella tubes and air-conditioner drip trays to prevent any water accumulation.

The FEHD also advises members of the public and property management companies to keep drains free of blockage and level all defective ground surfaces to prevent the water accumulation. They should also scrub all drains and surface sewers with alkaline detergents at least once a week to remove any mosquito eggs.

The public should call 1823 in case of mosquito problems and may visit the Centre for Health Protection's thematic webpage: www.chp.gov.hk/en/features/109029.html for more information on chikungunya fever.
