香港卫生署中心呼吁公众及时接种最新新冠疫苗，因为距离上次感染高峰已过去五个月多，下一次病毒浪潮即将到来。中心表示，新冠活跃期每六至九个月循环一次，与主导毒株变化和群体免疫力下降有关。
香港卫生保护中心于周五表示，新冠病毒的活跃期通常每六至九个月出现一次。最近一次感染高峰已过去五个月多，因此呼吁民众接种疫苗，以降低严重疾病和死亡风险。
中心控制员崔乐健博士表示：“根据中心的分析，活跃期与主导循环毒株的变化以及香港群体免疫力的下降有关。”
自三月底以来，当地主导毒株已从KP.2和KP.3转变为NB.1.8.1。最新监测数据显示，NB.1.8.1和LP.8.1目前在社区共同循环。
世界卫生组织的相关指导也支持及时接种疫苗，以应对新兴变异株。香港当局强调，疫苗接种是预防重症的有效措施，尤其在免疫力下降的时期。
这一呼吁旨在提醒公众保持警惕，尽管整体疫情已趋于稳定，但周期性波动仍需关注。

香港卫生当局呼吁居民接种最新季节性流感疫苗，以应对潜在的冬季流感浪潮，城市气温降至本季最低。卫生防护中心的呼吁与一位传染病专家对社区低疫苗接种率的担忧相呼应。最近数据显示，夏季流感季节正在结束。
Chile's Ministry of Health, through the Public Health Institute, confirmed the detection of the first cases of influenza A (H3N2) sub-clade K, known as “supergripe”, in analyzed samples in the country. This finding was expected given the virus's global behavior, already detected in Brazil and Peru. Health Minister Ximena Aguilera clarified that it is not a new virus or a pandemic.

Researchers at Columbia University’s Mailman School of Public Health used computer simulations to reconstruct how the 2009 H1N1 influenza pandemic and the 2020 COVID-19 pandemic expanded across U.S. metropolitan areas. The study, published in the Proceedings of the National Academy of Sciences, found that both viruses were already circulating widely in many cities within weeks, with air travel playing a larger role than daily commuting. The authors said broader wastewater surveillance, paired with infection-control measures, could help slow early spread in future outbreaks.
