Turkey has recorded 37,303 new coronavirus cases in the space of 24 hours, the highest number since the beginning of the pandemic more than a year ago, health ministry data showed on Tuesday.
The government had said on Monday it would tighten restrictions on movement and gatherings because of rising infections, less than a month after easing them.
President Tayyip Erdogan announced the tightening, including the return of full nationwide weekend lockdowns for the holy Islamic month of Ramadan.
The latest daily death toll was 155, bringing the cumulative toll to 31,385, according to the data.
Health Minister Fahrettin Koca told reporters in parliament that new variants of the coronavirus, which officials have blamed for the spike in infections, had now been seen in every province.
“Currently, the rate of the mutations in Turkey has reached some 75%. In some provinces, it is at around 50-55%, but there are provinces where it is at 95%,” Koca said.
Most were of the variant first identified in Britain, with much smaller numbers of those first identified in South Africa and Brazil, Koca said.
