The WHO supports face shields as a tool to curb coronavirus spread, but warns that no face covering will stop the virus entirely

In a shift, the WHO now says the general public may want to use homemade face masks while out in public.  The WHO said Monday that “there is a role for face shields” too in providing protection against coronavirus infection, especially if face masks aren’t widely available. But, the agency cautioned that “masks alone will not protect you, face shields alone will not protect you from infection.” Officials stressed that social distancing, hand washing, and sneezing into your elbow if you’re sick are still important infection prevention measures for this virus.  Visit Business Insider’s homepage for more stories.
