With coronavirus cases ramping up in a number of US states, more and more US governors have issued mandates to wear masks while in public settings.
The continued spike in COVID-19 cases has caused several states to close bars and pause plans to reopen some businesses such as movie theaters.
While a number of states had previously mandated masks in many public spaces, several more have been added to the list in recent days. Requiring face coverings are largely being seen as a way to avoid reinstituting stay-at-home orders, which most states implemented during the spring.
Researchers from the University of Washington say that a projected 33,000 American lives would be saved between June 23 and October 1 if 95% of the population wore masks in public settings.
A study in the Lancet found that the use of masks and respirators by those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective.
