Christian Karagiannidis, the DIVI’s scientific head, said about 1,000 additional patients had ended up in intensive care since the middle of March. On Wednesday, 3,680 people were in intensive care in Germany, DIVI data show. “If this rate continues, we will reach the regular capacity limit in less than four weeks,” he told the Rheinische Post daily. The number of confirmed coronavirus cases rose 24,300 to 2.833 million on Thursday, the biggest increase since Jan. 14. Karagiannidis called for a hard lockdown for two weeks, compulsory tests at schools twice a week and much faster shots at vaccination centres and doctors’ practices.
