Angela Merkel's initial test for coronavirus has returned a negative result, but the German leader's spokesman, Steffen Seibert, told news agency Deutsche Presse-Agentur that "further tests will be conducted in the coming days".
Chancellor Merkel went into quarantine on Sunday after being informed that a doctor who had administered a vaccination to her had contracted Covid-19.
She received the precautionary vaccination against pneumococcal infection on Friday. The 65-year-old, who has led Germany since 2005, was informed about the doctor's test shortly after holding a news conference announcing new measures to curb the spread of the virus.
