PCR results, shotgun RNA sequencing results, and physician’s diagnosis in individuals with symptoms of respiratory infection (n = 52).

Individuals not included here (n = 45) had symptoms of respiratory infection, but did not have a physician’s diagnosis or a POC test, and were negative by both PCR and/or sequencing. Two individuals did not have symptoms, or a diagnosis, of upper respiratory infection, but were positive for a virus. Five additional individuals were given a diagnosis of upper respiratory tract infection even though they did not present with upper respiratory infection symptoms focused on here.

未纳入本研究的个体（n=45）均存在呼吸道感染症状，但未获得医师诊断，亦未接受即时检验（Point-of-Care test，POC test），且经聚合酶链式反应（Polymerase Chain Reaction，PCR）及/或测序检测均为阴性。另有2名个体既无上呼吸道感染症状，也无相关诊断史，但病毒检测结果呈阳性。另有5名个体被诊断为上呼吸道感染，尽管他们未表现出本次研究重点关注的上呼吸道感染相关症状。
