In light of the serious public health threat posed by mosquito-borne diseases, the Government has been keeping up and strengthening its mosquito prevention and control measures, and called on members of the public to co-operate and attach importance to household and environmental hygiene with a view to preventing mosquito breeding.

The Permanent Secretary for Food and Health (Food), Mrs Cherry Tse, today (March 24) chaired a meeting of the Anti-Mosquito Steering Committee (AMSC) to review the effectiveness of measures taken by the relevant bureaux and departments in tackling the mosquito problem. The AMSC also discussed ways to enhance co-operation among different departments to intensify anti-mosquito work.

"At present, there is no vaccine against dengue fever and the Zika virus infection on the market, and hence, keeping the environment clean to eliminate mosquito breeding and avoiding mosquito bites are the only ways to prevent infection. In fact, in response to the high incidence of dengue fever cases occurring in neighbouring areas, mosquito prevention and control measures had been stepped up in the 18 districts continuously in the past two years. As the Zika virus infection, which can also be transmitted by mosquitoes, has recently aroused public concern, and Hong Kong will soon enter the summer season, the relevant departments will further step up anti-mosquito work," Mrs Tse said.

In monitoring the dengue vector, the Food and Environmental Hygiene Department (FEHD) has since October 2015 increased the number of surveillance areas with ovitraps for Aedes albopictus from 44 to 52. As for the Japanese encephalitis vector surveillance programme, the surveillance work which was first carried out in the relatively high-risk Yuen Long district from April to October each year has since been extended to cover Tuen Mun, North District, Sai Kung, Kwai Tsing, Southern District and Sham Shui Po throughout the year. The FEHD will also pay special attention to those areas which are prone to mosquito breeding, such as soil fill in rural areas, and carry out inspections and take appropriate measures to prevent mosquito breeding. In 2015, the FEHD instigated 61 prosecutions against mosquito breeding in premises according to the Public Health and Municipal Services Ordinance (Cap. 132), among which 29 involved construction sites. In addition, the department’s professional staff will closely monitor the mosquito management approach adopted by other places, including advances in technology relating to the use of genetically modified mosquitoes to eliminate mosquitoes breeding.

Other departments have continued to intensify their anti-mosquito work. The Agriculture, Fisheries and Conservation Department has stepped up the inspections and mosquito prevention work in facilities under its management, including country parks, Hong Kong Wetland Park and government wholesale markets. The department has also taken steps to remind park visitors and market tenants of the importance of adopting anti-mosquito measures, keeping the venues clean and clearing stagnant water.

Having regard to mosquito breeding in construction sites, the Development Bureau (DEVB) has reminded the contractors of public works sites to carry out anti-mosquito measures in the construction sites. The bureau, through contractors’ association, has also encouraged contractors of private projects to actively participate in anti-mosquito work. According to the existing regulatory mechanism, the qualification of the contractors on the List of Approved Contractors for Public Works to bid public works will be affected if they repeatedly breach anti-mosquito regulations. To further encourage contractors to carry out mosquito prevention and control work, the DEVB will consider strengthening the relevant penalty mechanism.

The Lands Department will step up the inspection of government land under its control, and conduct cleansing work and grass cutting when necessary. The department will also clear identified hillside illegal cultivation black spots to eliminate potential mosquito breeding grounds, and send letters to request short-term tenants to prevent and control mosquito breeding.

The Education Bureau and FEHD will jointly organise a seminar on the prevention of dengue fever and other mosquito-borne diseases on May 6 in order to enhance awareness in schools and disseminate messages on preventing the spread of mosquito-borne virus in campus.

The Leisure and Cultural Services Department will continue to carry out mosquito control operation in its venues, and step up the relevant measures in individual venues according to the actual situation and need.

The Housing Department will publicise anti-mosquito messages through posters, notices, and estate newsletters.

The Government Property Agency has tasked its property management agents to continue to take appropriate anti-mosquito measures, including strengthening inspections, preventing the accumulation and clearing of stagnant water, cutting grass and applying larvicidal oil as well as stepping up the publicity for mosquito prevention and control.

The District Offices will assist with the publicity for mosquito prevention and control, such as distributing the relevant promotional leaflets and items, as well as facilitating health talks, in order to arouse community awareness and to promote participation in anti-mosquito work.

In light of growing number of Zika virus infection cases reported around the world, the Department of Health (DH) will maintain close liaison with the World Health Organization as well as overseas, neighbouring regions and Mainland health authorities to closely monitor the latest developments of Zika virus infection. The Alert Response Level under the Government's Preparedness and Response Plan for the Zika Virus Infection has also activated. The DH will continue to furnish the public with advice on infection prevention, in the light of the latest prevailing circumstances.

Mrs Tse said apart from anti-mosquito measures adopted by various government departments, the concerted efforts of the community are also important to the successful implementation of mosquito prevention and control work.

She appealed to the public for enhanced efforts to inspect their homes and surroundings to remove potential breeding grounds. Members of the public and estate management bodies are well advised to keep drains free of blockage and fill up all depressions to prevent puddles from forming. Should members of the public come across mosquito-breeding spots that require attention, they may report to the relevant government departments via 1823.

All local residents, be they in Hong Kong or travelling outside the territory, should take precautionary measures to prevent infection by vector-borne diseases, as well as vector proliferation. They are well advised to 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. Travellers returning to Hong Kong 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 relevant bureaux and departments will maintain close communication with each other and act in concert to fully implement mosquito prevention and control measures. We also hope that the related sectors, especially the construction sector, and the public will chip in and complement the efforts made by the Government to eliminate mosquito breeding," Mrs Tse said.
