dc.description.abstractViral RNA in fine (< 5 m) aerosols from 13 patients infected by the SARS-CoV-2 virus were obtained using the Gesundheit-II (G-II) equipment which collects respiratory emissions. The collection was performed in isolation wards of the National Centre for Infectious Diseases of Singapore under an approved protocol. The patients breathed normally for 30 minutes, talk, and sing for 15 minutes each (with 30 minutes rest in between activity) into a specially designed aerosol collector in two size fractions. The coarse fraction (> 5 m) and the fine aerosols (< 5 m) are subsequently collected and subjected to PCR analysis for their viral load quantification. Viral RNA detected from 59% of the patients showed that patients earlier in illness were more likely to emit detectable RNA, and loads differed significantly between breathing, talking, and singing.
