Polish President Andrzej Duda has tested positive for coronavirus but is feeling well, presidential spokesperson Blazej Spychalski announced Saturday.
"The president yesterday was tested for the presence of coronavirus. The result turned out to be positive. The president is fine. We are in constant contact with the relevant medical services," Spychalski said on Twitter.
While it was unclear when Duda was infected, he had attended an investment forum in Tallinn on Monday where he met with Bulgarian President Rumen Radev who later went into quarantine.
Duda's infection comes as the country faces a surge in the COVID-19 epidemic, with new infections hitting a daily record of more than 13,600 on Friday.
Duda, 48, holds a mainly ceremonial role, but has the power to veto legislation. He is an ally of the ruling nationalist Law and Justice (PiS) party.
From Saturday, more restrictions to curb the spread of the virus are due to come into force in Poland, including a two-week shutdown of restaurants and bars.
The move came as the EU country of 38 million people saw a new 24-hour record of 13,632 coronavirus cases on Friday.
Poles have been asked to work remotely if they can and primary schools are partially closed with only grades one to three attending classes.

Restaurants, cafes and pubs are only be able to serve take-away meals. Fitness clubs and pools are also closed.
Gatherings are limited to five people, with weddings banned and strict limits on the numbers of people allowed in shops, on public transport and at religious services.
Poland's national stadium is being transformed into a field hospital for Warsaw and the government is building temporary medical facilities elsewhere, as the surge in coronavirus cases strains healthcare facilities to breaking point.
