The number of people infected with coronavirus in Germany has “stabilised”, the public health chief said Tuesday, as politicians prepare for talks on when to end the lockdown measures used to slow the disease’s spread. “Numbers have stabilised at a relatively high level,” Lothar Wieler of the Robert Koch Institute (RKI) for disease control told reporters. Politicians are waiting on every comment by the country’s leading medical experts, as Chancellor Angela Merkel will hold a conference Wednesday with state premiers on whether and for how long to extend infection control measures.
