Wired: It’s Time to Face Facts, America: Masks Work

The collective evidence makes a strong case for universal mask wearing during a pandemic. Masks are not a substitute for other interventions; they must always be used in combination with social distancing and hand hygiene. But even during a lockdown, some people need to leave their homes for essential task, such as buying food and medicine. With diseases like Covid-19, many individuals may be infected but asymptomatic, spreading the virus without realizing it. In parallel, some healthy people may not be able to adequately isolate themselves from infected partners, family members, and housemates. Masks could help reduce the spread of disease in all these scenarios. “Masks work in both directions,” virologist Julian Tang explained. “If everybody wears a mask, it’s double protection. Even if a mask is not 100 percent sealed, it is still a significant reduction in risk of transmission.” Article Link: https://www.wired.com/story/its-time-to-face-facts-america-masks-work/
