Prime Minister Sanna Marin (the SDP) has returned back to work.

“I will still have to save my voice because of a stubborn cough, ” she says on Twitter on Monday. “But otherwise I will handle my work-related tasks normally.”
Prime Minister Marin has been on sick leave since last Monday.
Last week, the government’s office stated that “A coronavirus test was taken from the prime minister to be on the safe side. The result is negative.”
