The FEHD continues to carry out a series of mosquito prevention and elimination measures, including:

• interdepartmental collaboration: convening special meetings of the interdepartmental task forces on anti-mosquito work to co-ordinate relevant departments and stakeholders (such as construction site contractors, schools and property management companies) in strengthening mosquito control work at venues;

• precise risk assessments: carrying out intensive and targeted mosquito control work at locations with more serious mosquito infestations, including stepping up inspections, eliminating mosquito breeding and potential breeding grounds, applying larvicides, conducting fogging operations to eradicate adult mosquitoes, and placing mosquito trapping devices at appropriate locations;

• promotion and education: organising exhibitions with relevant departments and stakeholders, and distributing leaflets and posters to enhance public awareness of mosquito control and prevention; and

• rapid alert mechanism: notifying residential estates that have subscribed to the gravidtrap Rapid Alert System, and advising property management companies and residents to stay vigilant and work together in taking mosquito prevention and elimination measures.

During the follow-up actions and following the discovery of stagnant water or stagnant water containers at a construction site and a park in Eastern District and Kowloon City District, the FEHD has issued a total of two statutory notices to the responsible persons-in-charge, requiring the clearance of such items within a specified timeframe.

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:

• tidying up their premises and checking for any accumulation of water inside the premises;

• removing all unnecessary water collections and eliminating the sources;

• checking 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;

• changing water in flower vases and scrubbing their inner surfaces thoroughly, and removing water in saucers under potted plants at least once a week;

• properly covering all containers that hold water to prevent mosquitoes from accessing the water;

• properly disposing of articles that can contain water, such as disposable meal boxes and empty cans; and

• scrubbing 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. At present, the FEHD has set up gravidtraps in 62 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#).

Northern Metropolis Financial Advisory Taskforce holds its third meeting

The following is issued on behalf of the Hong Kong Monetary Authority:

The Northern Metropolis Financial Advisory Taskforce (Taskforce), jointly established by the Hong Kong Monetary Authority (HKMA) and The Hong Kong Association of Banks (HKAB), convened its third meeting today (November 10). Meeting participants included representatives from the HKMA, the HKAB, the Development Bureau, the Education Bureau (EDB), The Financial Services and the Treasury Bureau, the Innovation, Technology and Industry Bureau and 25 participating banks in the Taskforce (see Annex).

At the meeting, the EDB presented the latest development of the Northern Metropolis University Town (NMUT), including the positioning of the three university towns (Note), development of campus areas and related financial arrangements. Meeting participants discussed and offered professional advice on feasible financing solutions for the NMUT Area, such as loans and public-private partnerships. The participating banks in the Taskforce expressed their commitment to provide suitable financial services to support the synergistic development of the NMUT and its surrounding industry parks and projects.

To further strengthen the banking sector's financing support for Northern Metropolis (NM) projects, the HKMA proposes to amend the Banking (Capital) Rules to designate government-related entities, including 11 post-secondary institutions and three park companies, as Domestic Public Sector Entities. This measure will help lower banks' capital costs, assist these entities in obtaining bank financing, and thereby accelerate the implementation of NM projects. The HKMA intends to submit the amendments to the Legislative Council in the first quarter of 2027, with a view to their taking effect in the second quarter of the same year.

Northern Metropolis Financial Advisory Taskforce

The Northern Metropolis Financial Advisory Taskforce was jointly established by the HKMA and the HKAB in April 2026 to strengthen the banking sector's communication and collaboration with the Hong Kong Special Administrative Region Government and other stakeholders and explore ways to actively support the Northern Metropolis development through financing. The Taskforce comprises representatives from the HKMA, the HKAB and 25 banks that possess experience in large-scale project financing. The Chinese Banking Association of Hong Kong and the Infrastructure Financing and Securitisation Unit of the Hong Kong Mortgage Corporation Limited participate as observers.
