Poland’s President Andrzej Duda has tested positive for COVID-19.
His spokesperson Blazej Spychalski tweeted that the conservative leader received the result after taking a test on Friday.
Mr Spychalski says the president feels well and will be in quarantine.
Mr Duda’s diagnosis follows a sharp increase in the confirmed cases of COVID-19 and related deaths in the country.
On Friday, 13,600 new infections were recorded in Poland – a new record. There were also 153 deaths, taking the total related to COVID-19 to 4,162.
The Polish government has announced the entire country will become a “red zone” of strict measures – just short of a national lockdown – as it attempts to curb the spread of the virus.
Elsewhere in Europe, French President Emmanuel Macron has called on citizens to respect the nightly curfew and other measures as cases rapidly rise.
Mr Macron said cases are “very strongly accelerating” – with COVID-19 patients occupying more than 42% of ICU beds nationally and 64% in Paris.
He has also said that scientists have told him they think the virus will be present “at best until next summer” – and that it is too soon to say whether France will enter into a full or partial lockdown.
Italy has reached a new daily high of almost 20,000 COVID cases – with those needing intensive care surpassing 1,000.
Hospitals say they can handle the cases at the moment.
