Influenza virus can survive on some surfaces, facilitating indirect person-to-person transmission.
We collected swab samples weekly from commonly touched surfaces in 7 kindergartens and primary schools during the 2017/2018 winter influenza season in Hong Kong.
We detected influenza virus ribonucleic acid (RNA) in 12 of 1352 samples (<1%) collected from 7 of 11 classrooms (5 to 2 × 106 RNA copies/mL). Viral RNA was more frequently recovered from communal items inside classrooms such as bookshelves and doorknobs.
Surface contamination indicates the potential role of fomites in influenza virus transmission in schools. Communal items inside classrooms may cause greater potential risks of transmission during influenza epidemics.
流感病毒可以在某些表面存活，从而促进间接的人际传播。
在 2017/2018 年冬季流感季节，我们每周从香港 7 所幼儿园和小学中经常触摸的表面采集拭子样本。
我们从 11 间教室中的 7 间采集的 1352 个样本中（<1%）检测到了 12 个样本含有流感病毒核糖核酸（RNA）（5 至 2×106 RNA 拷贝/mL）。病毒 RNA 更频繁地从教室内部的公共物品中回收，例如书架和门把手。
表面污染表明污染物在学校流感病毒传播中的潜在作用。教室内的公共物品在流感流行期间可能会造成更大的传播潜在风险。
