Currently, 33,376 people are self-isolating and 1,337 are receiving hospital treatment, including 144 who are on ventilators.
"A total of 6,832 persons have been infected this week alone, and compared with the start of last month, the number of patients on ventilators has nearly doubled and the number of hospital patients has increased by 60%," Beroš said.
By Wednesday, 2,632 samples have been sent for sequencing and the results show that the British variant of the coronavirus was detected in 67% of them.
Croatia has so far received 540,845 vaccine doses, and by 30 March 463,003 doses have been administered, or 86% of the doses received.
Beroš said that additional intensive care units are being reopened in the Dubrava Hospital in Zagreb, as well as in other hospitals as necessary.
He called on the citizens to refrain from large gatherings during the Easter holidays, to maintain a safe distance, wear masks and air out their rooms.
In the last 24 hours, there have been 20 COVID-related deaths bringing the death toll to 5,967.
The head of the national coronavirus response team, Interior Minister Davor Božinović, spoke of the measures to contain the coronavirus, which are being tightened until 15 April.
"Given the fact that the epidemiological situation is not the same everywhere, the national response team is introducing the new measures for the large part at the proposal of county teams," Božinović said.
Over the next two weeks, indoor training will be forbidden at national level, except for top athletes, and the work of indoor play groups will be restricted.
As for the border crossing regime, for entry into Croatia fast antigen tests, recognised by EU member states, and vaccination certificates will be recognised.
