"President Andrzej Duda was tested for coronavirus yesterday, in line with recommendations. The result was positive. The president is feeling fine. We are in constant contact with relevant medical services," Spychalski tweeted.
In another Twitter post, Spychalski said he himself was going to be quarantined.
Duda's chief aide, Krzysztof Szczerski, said on Saturday that a list of the president's recent contacts will be drawn up. On Friday, Duda visited Warsaw's National Stadium, which is being turned into a makeshift COVID-19 hospital with 500 beds.
Deputy Health Minister Waldemar Kraska told private radio broadcaster RMF FM on Saturday morning that the president is in a good condition. "We believe that his infection should be mild as he is a young person, so I think he will cope with it very well. As you can see, the virus is not selective. Anyone can contract it, so our appeals to observe the regime are so appropriate," Kraska said.
The deputy minister expressed the belief that the construction of the National Stadium hospital is not at risk. "Everyone was wearing masks, keeping their distance, so the risk of infection is minor. But certainly persons who had contact with the president will be tested," he said, adding that the works should be completed in a few days' time.
Also on Friday, Duda met with young Polish tennis star Iga Swiatek to offer her a state distinction. "I think Iga Swiatek will also be quarantined," Kraska said.
On Friday, the Polish Health Ministry reported a record number of daily coronavirus infections at 13,632, with 153 fatalities. So far, Poland has seen a total of 228,318 infections and 4,172 deaths from the disease. (PAP)
