<abstract>Certain respiratory tract infections are transmitted through air. Coughing and sneezing by an infected person can emit pathogen-containing particles with diameters less than 10 um that can reach the aleveolar region. Based on our analysis of the sparse literature on respiratory aerosols, we estimated that emitted particles quickly decrease in diameters due to water loss to one-half the initial values, and that in one cough the volume in particles with initital diameters less than 20 um is 6 x 10 -8 mL</abstract>
