ATHENS — Greece’s health minister says new measures will be announced to curb the spread of the coronavirus, after an alarming spike in the number of new daily confirmed cases and the number of people severely ill with Covid-19.

Speaking after a meeting with health and government officials Monday, Vassilis Kikilias appealed to Greeks, particularly to young people, to ensure they adhere to protective measures such as wearing masks and maintaining social distance.

New daily confirmed infections have been above 150 for the past four days, with 203 new cases announced on Sunday, compared to 152 the previous day.

“Unfortunately, the transmission of the virus presents dangerously increasing tendencies,” Kikilias said. “Once more I appeal to young people and to citizens who are not adhering to personal protective measures … to consider their responsibility toward vulnerable groups, our other citizens and toward the country.”

Greece currently has 5,623 confirmed coronavirus cases and 212 deaths, with 22 people intubated in intensive care units.
