Summer Influenza Season Ends; CHP Urges Vaccination Ahead of Winter Surge

DH urges public to stay vigilant as summer influenza season concludes while winter influenza season approaches

The Centre for Health Protection (CHP) of the Department of Health (DH) today (January 8) announced that the summer influenza season has concluded. Seasonal influenza activity has continued to decline in the past few weeks and dropped below the baseline levels during the most recent week. However, influenza activity may rise again as the weather gradually turns colder. With the winter influenza season approaching, the CHP strongly urged those who have not yet received the 2025/26 seasonal influenza vaccination (SIV), particularly high-risk groups such as pregnant women, the elderly, children and those with chronic illnesses. These groups should receive their SIV promptly to reduce the risk of severe illness and death from infection.

Summer influenza season concludes and winter influenza season approaches

--------------------------------------------------------------------------------------

"Hong Kong entered the summer influenza season in early September last year. Seasonal influenza activity peaked in mid-to-late October last year and has since been gradually declining. The latest surveillance data shows that the percentage of respiratory specimens tested positive for seasonal influenza viruses during the most recent week (December 28, 2025, to January 3, 2026) was 4.08 per cent, while the influenza admission rate in public hospitals was 0.23 cases per 10 000 population. As both indicators have dropped below the baseline levels (i.e. 4.94 per cent and 0.27 cases per 10 000 population respectively), the CHP confirmed that the summer influenza season has ended. Hong Kong entered the summer influenza season in September last year and it has lasted about four months. The summer influenza season started later than usual," the Controller of the CHP, Dr Edwin Tsui, said.

The predominant virus circulating during this seasonal influenza season was the influenza A (H3) virus strain. As in the past, severe or fatal cases associated with seasonal influenza primarily affect the elderly and children. This summer influenza season recorded 25 severe paediatric influenza cases, including three fatal cases. The affected children were aged between 6 months to 17 years old. Among them, 20 cases (80 per cent) had not received an SIV (including one case who received the 2025/26 SIV only four days before onset of illness. As it generally takes two weeks for the body to develop sufficient protection after vaccination, the case was not protected by the vaccine. Therefore, it is not counted as being vaccinated). During the same period, 507 severe influenza cases were recorded among adults, including 342 deaths. About 80 per cent of severe adult influenza cases involved elderly persons aged 65 or above while over 70 per cent of the patients did not receive an SIV.

"This summer influenza season has ended, meaning there was no overlap between the summer and winter influenza seasons. However, influenza activity may rise again as the weather gradually turns colder in the first quarter of this year and it cannot be ruled out that the circulating virus strains may change as the winter influenza season approaches. Therefore, I once again urge all individuals aged 6 months or older, except those with known contraindications, to act promptly if they have not yet received an SIV. This includes those who contracted influenza during the summer influenza season in order to guard against other circulating virus strains that may emerge during the upcoming winter influenza season. Furthermore, although there are some antigenic differences between the currently circulating influenza A (H3) virus strain and the virus strain contained in the vaccine, an SIV can still offer protection against the variant strain of subclade K, as well as the influenza A (H1) and influenza B strains included in the vaccine," Dr Tsui said.

"Influenza seasons started earlier than usual in multiple regions worldwide last year. Influenza activity in the United States remains at high level and continues to increase, with approximately 11 million persons infected, 120 000 hospitalisations, and 5 000 deaths recorded this season. Influenza activity is anticipated to continue for several more weeks. Meanwhile, influenza activity has recently begun to decline on the Chinese Mainland, in the United Kingdom, South Korea, and Japan," he added.

2025/26 SIV Programmes

------------------------------

Getting vaccinated against influenza is one of the most effective ways to prevent influenza and its complications. It also reduces the risk of serious illness or death from infection. With the concerted efforts of all sectors of the community (including the medical sector, schools, parents and residential care homes), as of January 4, over 1.91 million doses of influenza vaccine were administered under various SIV programmes in the year 2025/26, representing an increase of approximately 4.4 per cent compared with the same period in the previous influenza vaccination season. Regarding schools, vaccination rates among schoolchildren in different age groups are 2 to 10 percentage points higher compared to the same period last year.

"Although the influenza activity has declined to below the baseline level at the moment, sporadic outbreaks caused by influenza viruses are still possible in schools and residential care homes. For children who did not join the SIV School Outreach Programme, parents should promptly bring their children to private doctors enrolled in the Vaccination Subsidy Scheme to receive an SIV. Moreover, residents and staff of residential care homes for the elderly should get vaccinated promptly. In addition, the SIV coverage rate for children aged 6 months to under 2 years is only about 22 per cent. Although this represents an approximate 5 percentage point increase compared to the same period last year, it is still much lower than that of other age groups. Through the Primary Healthcare Commission, the CHP has urged family doctors to assist in encouraging parents to allow their children to receive an SIV," Dr Tsui said.

The Government has opened all 29 of the DH's Maternal and Child Health Centres (MCHCs) for all children aged 6 months to under 2 years to receive the vaccine; as well as the District Health Centres and District Health Centre Expresses and their service outlets under the Primary Healthcare Commission in the 18 districts, 75 Family Medicine Clinics and 38 public hospitals of the Hospital Authority to provide more choices for the public. For the list of vaccination venues, please refer to the CHP's Vaccination Schemes page. Parents of eligible children may book an appointment for their children to receive vaccination at designated MCHCs via the online booking system.

Members of the public may refer to the CHP's COVID-19 & Flu Express,Seasonal Influenza Webpage, COVID-19 Vaccination Programme Webpage, and Vaccination Schemes Webpage, for the latest information.

Collecting preferences of Wang Fuk Court flat owners to advance long-term rehousing work

A Government spokesman said today (January 9) that social workers under the "one social worker per household" service of the Social Welfare Department (SWD) are proactively contacting flat owners of Wang Fuk Court, who were affected by the fire. They are comprehensively and systematically gathering each owner's preliminary preferences regarding long-term rehousing to assist in formulating and implementing specific plans.

The Chief Executive previously instructed the Task Force on Emergency Accommodation Arrangements to co-ordinate relevant policy bureaux and departments in studying long-term rehousing solutions. Adhering to the principles of "empathy, reason, and law", with priority given to "empathy", the Task Force aims to address the individual circumstances and preferences of residents while ensuring the efficient use of resources to assist affected households in rebuilding their homes.

The spokesman said, "Social workers from the SWD have been in contact with the residents, listening to their views, understanding their actual situations and needs, and providing necessary assistance. Regarding long-term accommodation, we have noticed differing opinions among flat owners and the community. For example, some hope that the Government will acquire the properties or give priority to Wang Fuk Court flat owners to purchase Home Ownership Scheme flats. Some residents seek local rehousing, while others accept rehousing in different districts. Some propose in-situ redevelopment, but there are also concerns about the lengthy waiting times.

"We hope to systematically and comprehensively collect Wang Fuk Court flat owners' opinions, further listening to and summarising their preferences. This includes identifying key principles that the Government should consider when addressing long-term accommodation arrangements and noting the flat owners’ initial preferences for different long-term rehousing options. This information will serve as a reference for the Government's follow-up actions."

Starting today, social workers under the SWD's "one social worker per household" service will begin contacting flat owners of Wang Fuk Court to gather their initial preferences regarding various long-term rehousing arrangements. The goal is to collect responses from the flat owners by mid-to-late January for analysis.

The spokesman said, "The Task Force will carefully compile and study the different preferences of flat owners and will conduct a comprehensive assessment based on the actual conditions at Wang Fuk Court, including structural safety, technical feasibility, and community planning. We aim to provide affected flat owners with suggestions regarding long-term proposals as soon as possible for their consideration and decision-making."

He said, "The Government and affected flat owners share a same objective: to implement solutions promptly and reassure them as soon as possible."

Following the fire, the Government arranged emergency accommodation for the affected residents of Wang Fuk Court in a short time frame. As of today, more than 4 400 residents are staying in hotels, youth hostels/camps, transitional housing, units from the Hong Kong Housing Society or Po Tin Interim Housing in Tuen Mun. Since December 22 last year, the Support Fund for Wang Fuk Court in Tai Po has provided each flat owner, in tranches, with a two-year rental subsidy up to a maximum of $300,000, giving them more flexibility and options in their accommodation arrangements.
