Earlier in the day Health Minister Constantinos Ioannou said he had called an urgent meeting of the advisory committee for Wednesday to discuss the situation.
The minister said he was very worried about the recent surge in coronavirus cases, after being briefed on the number, up until that moment, of new cases detected during the past 24 hours.
On Monday 41 cases were detected. The second highest daily number was 58 cases announced on April 1.
The health ministry said the transmission chains discovered during the past few days but also of the number of cases added to these chains means that the health protocols are not fully observed. As a result, the virus is spreading in workplaces and restaurants, and mainly in places frequented by young people.
There is also an increase in the number of people tested after presenting symptoms. “This sounds the alarm for us as the increase of symptomatic coronavirus carriers shows the possibility of an increase in the people who will need hospitalisation in the next period is also very high,” he said.
It also recalled that last week three people died in four days “which is also worrying.”
The total number of cases is now at 2,130.
