Finland's President Sauli Niinisto is being examined in hospital due to his prolonged COVID-19 symptoms, the president's office said on Tuesday.
"The President of the Republic's condition is reasonably good," it said in a statement, adding he would continue to work remotely.
Niinisto, 73, tested positive for coronavirus a week ago on Tuesday.
Finland is in the middle of considering joining NATO and Niinisto plays a central role in the process, which is expected to come to a conclusion within weeks.
