Greece confirmed 882 new COVID-19 cases on Thursday, 99 of which are known to known clusters, setting a new negative record for the third consecutive day.

Seeing the rising threat, Greece’s Prime Minister Kyriakos Mitsotakis set a curfew from 00.30 to 5am as of Saturday night in areas of Level 3 (increased monitoring) and Level 4 (increased threat).

Night-shift workers and those suffering from emergency incidents are exempt from the curfew which is aimed at seeing a “reduction in gatherings at night”. Mr Mitsotakis explained that partial curfews were already in effect in several European cities.

Mr Mitsotakis also made the wearing of face masks mandatory, indoors and outdoors. He said face masks were “the cure before the vaccine”. Wearing face masks is already obligatory in all indoor public areas in Greece.

“To put it plainly,” he said, “from now on a mask is required to enter a cafe or restaurant. The mask may be removed only after we are seated. And, of course, the ban on clientele standing only in closed spaces is still in effect.”
