The number of new virus cases rose by 236 from the previous day, while the death toll increased by six, according to public health authorities.
The latest deaths in Poland’s coronavirus outbreak are two men in their 70s and four women aged 72 to 95, the Polish health ministry said in a tweet.
On Monday, the Polish health ministry reported 11 deaths throughout the day and 341 new coronavirus infections nationwide, compared with three deaths and 395 new cases a day earlier.
The health ministry announced on Tuesday morning that 2,171 people with suspected coronavirus infection were in hospitals nationwide, with a further 78,864 quarantined, and 19,139 under epidemiological supervision.
Meanwhile, 10,020 people have recovered from COVID-19 throughout the country, the health ministry also said.
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 banned public gatherings and closed all pubs, clubs and restaurants.
Health and government officials urged Poles to stay home and practice social distancing.
People have been ordered to wear masks or other face coverings when out in public.
Some restrictions were relaxed last month, and hotels and shopping malls were allowed to reopen in early May as the country moved to the next phase of easing its coronavirus lockdown.
Nurseries and preschools throughout the country have been given the green light to resume operations.
Poland has also reopened outdoor sports areas and allowed football matches to be played behind closed doors.
Hairdressers, beauty parlours, restaurants, bars and cafes were allowed to reopen to customers last week.
Polish elementary schools began reopening to young children on Monday as the country lifted more COVID-19 safety measures.
Meanwhile, regular classes at all levels of Polish schools remain suspended until at least June 7.
