A New Method for Sampling and Detection of Exhaled Respiratory Virus Aerosols

Abstract
We have developed a mask sampler for exhaled respiratory viruses. Among a group of 9 patients with cold symptoms who had virus-positive nasal mucus specimens, as analyzed by multiplexed polymerase chain reaction, virus-positive mask samples were obtained after coughing (20 times), talking (20 min), or breathing (20 min) from 6, 5, and 3 patients, respectively.
