Among the sixth batch of Area Gravidtrap Indexes covering 17 survey areas in January, all were below 10 per cent.

The FEHD has so far released six batches of gravidtrap indexes for Aedes albopictus in January 2026, covering 62 survey areas; most of the areas recorded 0 per cent, indicating that the distribution of Aedes albopictus mosquitoes was not extensive.

The eggs of Aedes albopictus can withstand long periods of desiccation and will hatch when the temperature becomes suitable and water is present. Members of the public should continue to take mosquito control measures during winter to eliminate mosquito eggs.

Public participation is crucial to the effective control of mosquito problems. The FEHD appeals to members of the public to continue to work together in strengthening personal mosquito control measures, including:

  • tidy up their premises and check for any accumulation of water inside their premises;
  • remove all unnecessary water collections and eliminate the sources;
  • check household items (those placed in outdoor and open areas in particular), such as refuse containers, vases, air conditioner drip trays, and laundry racks to prevent stagnant water;
  • change the water in flower vases and clear the water in saucers of potted plants at least once every seven days;
  • properly cover all containers that hold water to prevent mosquitoes from accessing the water;
  • properly dispose of articles that can contain water, such as empty lunch boxes and cans; and
  • scrub drains and surface sewers with alkaline detergent at least once a week to remove any mosquito eggs.
  • Starting in August 2025, following the completion of the surveillance of individual survey areas, and once the latest gravidtrap index and the density index are available, the FEHD has been disseminating relevant information through press releases, its website and social media. It aims to allow members of the public to quickly grasp the mosquito infestation situation and strengthen mosquito control efforts, thereby reducing the risk of chikungunya fever (CF) transmission.

    Following recommendations from the World Health Organization and taking into account the local situation in Hong Kong, the FEHD sets up gravidtraps in districts where mosquito-borne diseases have been recorded in the past, as well as in densely populated places such as housing estates, hospitals and schools to monitor the breeding and distribution of Aedes albopictus mosquitoes, which can transmit CF and dengue fever (DF). After reviewing the present DF and CF vector surveillance programme, the FEHD has expanded the coverage for monitoring Aedes albopictus mosquitoes starting from 2026. The number of survey areas set up in the community has been revised to 62, with some survey areas renamed. Additional gravidtraps will also be set up at different locations across the territory to strengthen the monitoring of the breeding of mosquitoes. Under the present surveillance mechanism, the FEHD has set up gravidtraps in survey areas of the community, with a surveillance period of two weeks. During the surveillance period, the FEHD will collect the gravidtraps once a week. After the first week of surveillance, the FEHD will immediately examine the glue boards inside the retrieved gravidtraps for the presence of adult Aedine mosquitoes to compile the Gravidtrap Index (First Phase) and Density Index (First Phase). At the end of the second week of surveillance, the FEHD will instantly check the glue boards for the presence of adult Aedine mosquitoes. Data from the two weeks of surveillance will be combined to obtain the Area Gravidtrap Index and the Area Density Index. The gravidtrap and density indexes for Aedes albopictus in different survey areas, as well as information on mosquito prevention and control measures, are available on the department's webpage (www.fehd.gov.hk/english/pestcontrol/dengue_fever/Dengue_Fever_Gravidtrap_Index_Update.html#).

    Remarks by FS at media session after attending Legislative Council Ante Chamber Exchange Session

    The Financial Secretary, Mr Paul Chan, met the media this morning (February 4) with Principal Officials, the President's Deputy of the Legislative Council, Mr Chan Chun-ying, and Chairmen of Legislative Council Panels, after attending the Legislative Council Ante Chamber Exchange Session. Following are the remarks by Mr Paul Chan:

    Reporter: What did you make of the earlier exchange sessions with the lawmakers? And as the Chief Executive said yesterday, Hong Kong will make its first Five-Year Plan following the 15th Five-Year Plan in Beijing, what are the intended directions on how to align with the nation's development goals? How will Hong Kong implement the relevant policies and will your Budget that comes out later this month seek to roll out policies that also align with the nation's directions?

    Financial Secretary: The discussion just now in the Ante Chamber focused on the 15th Five-Year Plan of the country. The recommendations for the 15th Five-Year Plan were set out last October. The final Plan will be released in March during the Two Sessions in Beijing. On the basis of those recommendations, in preparing the Budget, we have been taking into full consideration the future role of Hong Kong in aligning with, and making contributions to, the overall national development. During that process, Hong Kong will also benefit. For example, going forward - apart from being an international financial centre and international trade centre, technology and innovation will be a major driver of future economic growth.

    And the 15th Five-Year Plan puts emphasis on technological self-reliance, as well as deeply integrating technology with industrial development. These are also of high reference value for Hong Kong as we work to diversify our economic structure and create more quality jobs for our people. At the same time, it is also necessary to use technology to upgrade and empower different sectors. It is the policy of the Government to embrace technologies and apply them, in particular AI, across different sectors. In the upcoming Budget, content will certainly be devoted to this to outline the future economic direction of Hong Kong.

    For the five-year planning for Hong Kong to be led by the Chief Executive, it is indeed a great move. Going forward, the development of Hong Kong will count on the strong support of the Central Authorities, and the competitive advantages of Hong Kong as an international financial, trade and technology centre. We have a very big hinterland, which is a 1.4 billion-people market, as well as a vibrant technology and industry chain. We need to leverage these advantages to support our future growth. In the Budget, we'll also cover this aspect. Thank you.
