MedicalResearch.com: What are the main findings of the study?
Dr. Milton: We found that total viral copies detected by molecular methods were 8.8 times more numerous in fine (≤5 µm) than in coarse (>5 µm) aerosol particles and that the fine particles from cases with the highest total number of viral RNA copies contained infectious virus.
Surgical masks reduced the overall number of RNA copies by 3.4 fold.
