易感人群与感染者近距离接触时，呼吸道感染的暴露风险最高。自20世纪初以来，人们普遍认为大飞沫途径是大多数呼吸道感染的主要途径，相关的飞沫预防措施在医院和社区中广为人知并得到了实践。然而，令人惊讶的是，接触飞沫的机制仍未被探索。在这项研究中，在近距离接触时暴露于呼出的飞沫(
A susceptible person experiences the highest exposure risk of respiratory infection when he or she is in close proximity with an infected person. The large droplet route has been commonly believed to be dominant for most respiratory infections since the early 20th century, and the associated droplet precaution is widely known and practiced in hospitals and in the community. The mechanism of exposure to droplets expired at close contact, however, remains surprisingly unexplored. In this study, the exposure to exhaled droplets during close contact (
