香港卫生防护中心总监徐乐坚警告，随着疫苗接种率下降，且本市夏季流感季持续延长，流感感染风险增加。此前已有第二名未接种疫苗的儿童死于流感。
A senior Hong Kong health official has warned of a higher risk of influenza infection as vaccination rates fall and the city’s summer flu season stretches on, following the death of a second unvaccinated child from influenza.
香港目前的流感季始于6月，迟迟未见缓和迹象，徐乐坚因此发出上述警告。他表示，当局正在监测病毒传播方式在连续两个夏季流感季后是否发生变化。
Centre for Health Protection controller Edwin Tsui Lok-kin issued the warning as Hong Kong’s current flu season, which began in June, shows no sign of easing. He said authorities were monitoring possible changes in how the virus spreads after two consecutive summer flu seasons.
徐乐坚说：“自9月17日起，我们已接种超过90万剂流感疫苗。与去年同期接种100万剂相比，下降约10%。”
“Since September 17, we have administered more than 900,000 doses of the flu vaccine. Compared with the same period last year, when we had given one million doses, there has been a slight decrease of about 10 per cent,” Tsui said.
他说：“去年流感季在第18周左右基本结束。我们现在处于第16周左右，仍无减弱迹象。因此我预计今年流感季将比去年更长。”他将这一变化归因于病毒株的转变。
“Last year, the flu season was pretty much over by week 18. We are now at about week 16, with no sign of it waning. So I expect this year’s season to be longer than last year’s,” he said, attributing the change to a shift in the virus strain.
徐乐坚表示，他特别担忧就读幼儿园、幼稚园或小学的儿童，以及2至11岁人群的接种率下降。他们的接种率比去年低约5个百分点。
Tsui said he was particularly concerned about lower vaccination rates among children attending nursery, kindergarten or primary school, and among those aged two to 11. Their vaccination rate is about five percentage points lower than last year’s.
他说：“居家长者的接种率下降约1.8个百分点，而住院舍长者的接种率上升了3个百分点。”
“The rate among elderly people living at home has fallen by about 1.8 percentage points, while the rate among those living in care homes has risen by three percentage points,” he said.
香港流感季历来集中在冬季，过去10年中仅约一半年份出现夏季疫情。但本市今年和去年均经历了夏季流感季。
Hong Kong’s flu seasons were traditionally concentrated in winter, and summer outbreaks occurred in only about half of the past 10 years. But the city has now experienced summer flu seasons in this year and last year.
徐乐坚说：“新冠疫情后流感病毒传播模式的这一变化，需要我们用更多科学数据加以研究。”
“This change in the flu virus’s transmission patterns after the Covid-19 pandemic is something we need to examine with more scientific data,” Tsui said.
周二，一名未接种疫苗的12岁女孩成为香港本次流感季第二例死于甲型流感的儿童。她于周六首次出现症状，在心脏骤停后经复苏被送入儿科重症监护室。
On Tuesday, a 12-year-old unvaccinated girl became the second child to die from influenza A in Hong Kong during the current flu season. She first developed symptoms on Saturday and was admitted to a paediatric intensive care unit after suffering a cardiac arrest, from which she was resuscitated.
该女孩本身有基础疾病，周六出现发烧、咳嗽和腹泻，随后出现呕吐。其临床诊断为甲型流感感染并发感染性休克、弥散性血管内凝血和多器官衰竭。
The girl, who had underlying health conditions, developed a fever, cough and diarrhoea on Saturday, followed by vomiting. Her clinical diagnosis was influenza A infection complicated by septic shock, disseminated intravascular coagulation and multi-organ failure.
今年8月，一名此前身体健康状况良好的七岁男孩也不幸去世。他曾接种2025-26年度季节性流感疫苗，其呼吸道样本检测呈甲型H3流感阳性。其临床诊断为甲型流感感染并发休克和脑病。
In August, a seven-year-old boy who had previously been in good health also died. He had received the 2025-26 seasonal influenza vaccine, and his respiratory specimen tested positive for influenza A(H3). His clinical diagnosis was influenza A infection complicated by shock and encephalopathy.
