Recently, a research that published on thelancet.com
found that the coronavirus can survive on the outer layer of mask for 7 days .
This is a huge caution to our daily personal protection during this pandemic.
This new coronavirus mainly transmitted through droplet and contact. Your mask helps you keep the droplet out. But you may still be infected through contact.
