The Centre for Health Protection (CHP) of the Department of Health (DH) today (October 22) recorded another severe paediatric influenza infection cases, the third this week. In light of the high level of school influenza outbreaks, the CHP wrote to all schools in Hong Kong again, urging them to implement preventive measures and manage influenza outbreaks according to the Guidelines on Prevention of Communicable Diseases. The CHP also called on the schools to complete the vaccination activities as soon as possible and will continue to proactively provide feasible assistance.

     The severe case involves an 11-year-old girl with good past health. She has developed a fever, cough and sore throat since October 19. She attended the Accident and Emergency Department of Yan Chai Hospital on October 21 and was subsequently transferred to Princess Margaret Hospital for admission. She is currently in serious condition. Her nasopharyngeal swab specimen tested positive for the influenza A virus upon laboratory testing. The clinical diagnosis was influenza A infection complicated with severe pneumonia. The girl has not yet received the 2025/26 seasonal influenza vaccination (SIV). Her household contacts are currently asymptomatic. Recently, 10 other students from different classes at her school contracted influenza. All had mild symptoms and none required hospitalisation.

     "Hong Kong has entered the summer influenza season. As in the past, severe or death cases associated with influenza this season primarily affect the elderly and children. However, compared to the winter influenza season earlier this year, children have been particularly affected this season and there has been more severe paediatric influenza infection cases. Including today's latest case, there have been 13 severe paediatric influenza cases since the start of the school year in September, including one fatal case. The affected children were between two and 17 years old, and 10 of them had good past health. A total of 602 school outbreaks have been reported since the start of the school year, including 64 cases in kindergartens/child care centres, 320 cases in primary schools and 218 cases in secondary schools. This number is far higher than the 88 cases recorded in the whole winter influenza season earlier this year," the Controller of the CHP, Dr Edwin Tsui, said.

     In addition to continuing to render full support to schools in arranging vaccination activities, the CHP sent another letter to schools today to remind them to strengthen prevention and control measures. These measures include using correct methods for cleaning and disinfecting campuses effectively, appropriately opening windows to improve ventilation in the campus, reminding teachers and students to pay attention to personal and hand hygiene. The CHP also recommends that teachers and students check their temperature daily before returning to school. If they develop symptoms or a fever, they should not go to school. Schools should immediately report suspected outbreaks (such as respiratory infections) to the CHP to facilitate follow-up.

     Dr Tsui reminded parents that the condition of children with influenza may deteriorate rapidly. Parents must pay close attention to their children's condition. They should go to the Accident and Emergency Department immediately if the child's condition deteriorates, for example if they develop symptoms such as shortness of breath, wheezing, blue lips, chest pain, confusion, persistent fever or convulsion. High-risk individuals should wear surgical masks when staying in crowded places. People with respiratory symptoms, even if mild, should wear a surgical mask and seek medical advice promptly. They should also consider whether to attend work or school.

     Regarding SIV Programmes, to boost SIV rates, enrolment for the SIV School Outreach Programme has started since the beginning of June this year, which was earlier than last year. With the concerted efforts of the Government and various community sectors (including the medical sector and schools), approximately 2 300 schools (99 per cent) are going to arrange SIV school outreach activities. Among these, over 1 330 schools (58 per cent) have scheduled to carry out the outreach activities by the end of this month, and over 2 170 schools (94 per cent) by the end of next month (November), which are respectively higher than last year's 45 per cent and 83 per cent.

     "Through the concerted efforts of schools and medical institutions, this season's school outreach activities will generally be completed earlier than last season's. Since the start of the school year, about 710 schools have held SIV school outreach activities, which is higher than of 560 compared to the same period in the last season. In addition, 23 schools have responded to the CHP's call to advance their outreach activities, originally scheduled for December this year or January next year, to be held by the end of next month. We understand that participating schools have to take into account various objective factors such as the school calendar and staffing when scheduling school outreach activities, and coordinate with participating medical teams on the appropriate time. Should schools encounter any difficulties in advancing their outreach activities, they may contact the CHP during office hours at 3975 4872 and we will provide full assistance," Dr Tsui added.

     Currently, over 770 000 doses of vaccines have been administered under the various SIV Programmes, representing a 5.2 per cent increase in coverage rate compared to last year. However, vaccination rates among children aged 6 months to under 2 years remain relatively low.

     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. Moreover, the District Health Centres and District Health Centre Expresses and their service outlets under the Primary Healthcare Commission in the 18 districts, and 74 Family Medicine Clinics and 38 public hospitals of the Hospital Authority to provide more choices for the public. For a 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 vaccinations at designated MCHCs via the online booking system.
