The new Covid December 2020 mutation in UK is believed to be 70% more contagious than the original version. Could one reason be that Airborne transmission by normal breathing is now a dominant form of transmission? If this is the case, then are standard masks insufficient for any indoor setting, and should face masks that have filtration capability of N95 (or even stronger) be made mandatory? And should we pursue a modification of the Covid vaccines?
