Prime Minister Sanna Marin (SDP) has moved to remote working at her official residence in Kesäranta as a precaution after a possible coronavirus exposure, the government's Communications Department said on Thursday.
The PM, who is said to be asymptomatic, will also undergo a coronavirus test.
Marin will continue her work schedule on Thursday as planned, which includes participating in a video conference with other EU heads of state. The talks are preparation for an extraordinary meeting of the European Council in Brussels on 24-25 September, concerning EU relations with Turkey and China, among other issues.
This is the fifth time the premier's working schedule has been disrupted by coronavirus fears.
In April, Marin went into self-isolation after an employee at the prime ministerial residence was found to have been in contact with an infected person, but the subsequent test proved to be negative.
One month later, all of Finland’s ministers, including the PM, switched to telecommuting when Minister of Social Affairs and Health Aino-Kaisa Pekonen and Minister of Employment Tuula Haatainen were thought to have been exposed to the virus during government talks.
Later in May the PM took a week long sick leave, which again included taking a coronavirus test, after developing flu-like symptoms.
In August, the Prime Minister announced a move to telecommuting after developed mild respiratory symptoms, and undertook a coronavirus test which proved to be negative.
