Prince Albert of Monaco has been infected with coronavirus.
It was announced he had tested positive at the start of this week.
A palace statement said there's no cause for concern and he is being monitored by his personal physician as well as specialists from the Princess Grace hospital.
It added that he continues to work from home and is in contact with the government and cabinet of Monaco.
The 62-year-old is the reigning monarch of the principality of Monaco.
He succeeded his father, Prince Rainier III, after he died in 2005.
Albert is thought to be the first monarch or head of state worldwide to have been diagnosed with coronavirus.
Monaco has been placed on lockdown amid the outbreak, with people only able to leave their homes for essential reasons.
Albert's wife called on the nation to limit social contact and respect quarantine measures, the statement added.
