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.

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#).

SCS visits Government Career Fair at Lingnan University

The Secretary for the Civil Service, Mrs Ingrid Yeung, together with the President of Lingnan University (LU), Professor Joe Qin, visited the Government Career Fair at the university today (September 29). Mrs Yeung encouraged university students to learn more about the work of various government departments, as well as the diverse employment opportunities, job requirements and promotion prospects offered by the Government to young people, and to plan ahead for their future.

The application period for this year's joint recruitment exercise for six graduate grades will close this Friday (October 2). Mrs Yeung reminded students of bachelor's degree programmes who are graduating in the academic year of 2026-27 or 2027-28 to seize the opportunity to submit online applications before the deadline.

The Government, in collaboration with LU, organised the career fair to provide university students with one-stop and practical recruitment information. Many students visited the booths in their spare time and took the opportunity to raise questions and exchange views with serving civil servants from various grades.

Mrs Yeung said, "As set out in the First Five-Year Plan for Economic and Social Development of the Hong Kong Special Administrative Region (2026-2030) we strive to build an efficient government. Through active recruitment and publicity, we will encourage talent with aspirations and commitment to join the Government. The roving career fairs held by the Government at 10 universities are one such example, which deepen the younger generation's understanding of government work on the one hand, and attract new blood who are keen to serve the public to join the Government on the other. Looking ahead, we will continue to strengthen civil service management and training, enhance the attractiveness of civil service jobs, and build a civil service team that is highly committed, dares to innovate, and moves with the times.

"The Civil Service Bureau (CSB) co-ordinates the provision of diversified internship opportunities for young people and university students by bureaux and departments annually. In 2026-27, the Government and public organisations will offer around 3 600 short-term internship placements. Students who aspire to pursue a career in public service may take the opportunity to broaden their horizons and better plan for their career development."

Those who aspire to serve the community and contribute to the country and Hong Kong may now apply for the posts of Administrative Officer, Executive Officer II, Assistant Information Officer (General), Assistant Trade Officer II, Management Services Officer II and Transport Officer II. Applicants must submit their applications through the online application system on the CSB website (www.csb.gov.hk). The application deadline is 11.59pm on October 2.
