Do Material Masks Work

According to some studies, ≈25%–50% of persons with COVID-19 have gentle instances or are asymptomatic and doubtlessly can transmit infection to others. So in areas of high transmission, masks use as source management might prevent spread of an infection from individuals with asymptomatic, presymptomatic, or gentle infections. If medical masks are prioritized for healthcare workers, most people can use cloth masks in its place. Second, masks may be used by healthy persons to protect them from acquiring respiratory infections; some randomized controlled trials have proven masks to be efficacious in closed group settings, with and with out the practice of hand hygiene .

But except you’re a frontline healthcare employee, this study doesn’t have much relevance to the precautions you should be taking over campus or elsewhere.
