The number of new virus cases rose by 461 from the previous day, while the death toll increased by 18, according to public health authorities.
On Thursday, the Polish health ministry reported 28 deaths throughout the day and 336 new coronavirus infections nationwide, compared with 23 deaths and 380 new cases a day earlier.
The first infection was confirmed by Polish authorities on March 4, while the country's first coronavirus fatality was announced on March 12.
Poland has since declared a "state of epidemic" and temporarily closed its borders to non-residents in a move to curb the spread of the illness.
International scheduled flights and passenger rail connections were suspended on March 15.
In another move to contain the spread of the COVID-19 epidemic, the government has limited the operations of shopping malls and closed all pubs, clubs and entertainment venues.
Public gatherings of more than two people have been banned.
Health and government officials have urged Poles to stay home and practice social distancing.
An initial two-week closure of the country’s schools has been extended until April 26.
Poles now have to wear face masks or scarves covering their nose and mouth when out in public.
