German Chancellor Angela Merkel is going into home quarantine immediately, after a doctor who gave her a vaccination on Friday has tested positive for coronavirus, Merkel's spokesman Steffen Seibert announced in a press statement on Sunday.

Seibert also stated that the chancellor will continuously be tested for coronavirus because a test at this early stage would not be reliable. Merkel will continue her full workload from her quarantine, Seibert added.

Earlier Sunday: Germany has implemented a "contact ban" rather than a full nationwide lockdown in an effort to curb the spread of coronavirus, Merkel said.

Merkel said in a press conference Sunday that the country would toughen measures and "reduce contact with people as much as possible."
