German Chancellor Angela Merkel will quarantine herself at home after being treated by a doctor who has since tested positive for the novel coronavirus, a government spokesman said yesterday.

"The Chancellor has decided to quarantine herself immediately at home. She will be tested regularly in the coming days... (and) fulfil her official business from home," Steffen Seibert said in a statement.

The doctor had visited Merkel Friday to vaccinate her against the pneumococcus bacteria. It could take some time to determine whether the chancellor is herself infected as "a test would not yet be fully conclusive," Seibert said.
