We identified seasonal human coronaviruses, influenza viruses and rhinoviruses in exhaled breath and coughs of children and adults with acute respiratory illness. Surgical face masks significantly reduced detection of influenza virus RNA in respiratory droplets and coronavirus RNA in aerosols, with a trend toward reduced detection of coronavirus RNA in respiratory droplets. Our results indicate that surgical face masks could prevent transmission of human coronaviruses and influenza viruses from symptomatic individuals.

呼出气中的呼吸道病毒脱落和口罩的功效。
我们在患有急性呼吸道疾病的儿童和成人的呼出气和咳嗽中发现了季节性人类冠状病毒、流感病毒和鼻病毒。外科口罩显着减少了呼吸道飞沫中流感病毒 RNA 和气溶胶中冠状病毒 RNA 的检测，并有减少呼吸道飞沫中冠状病毒 RNA 检测的趋势。我们的结果表明，外科口罩可以防止有症状的人传播人类冠状病毒和流感病毒。
