The alarming rise on Greece's viral cases prompted Prime Minister Kyriakos Mitsotakis on Thursday to announce the mandatory use of face masks in all public areas either closed or open.
In addition a curfew will be imposed from 12.30 a.m. to 5 a.m. as of Saturday in all prefectures with alert levels three and four which are the highest.
