Source control is a strategy for reducing disease transmission by blocking respiratory secretions produced through speaking, coughing, sneezing[1] or singing.[2] Surgical masks are commonly used for this purpose, with cloth face masks recommended for use by the public only in epidemic situations when there are shortages of surgical masks.[3][4] In addition, respiratory etiquette such as covering the mouth and nose with a tissue when coughing can be considered source control.[3] In diseases transmitted by droplets or aerosols, understanding air flow, particle and aerosol transport may lead to rational infrastructural source control measures that minimize exposure of susceptible persons.[5]
