Of the new cases confirmed on Thursday, 1,739 were in the central region of Mazowieckie, which includes the national capital Warsaw.
Meanwhile, 1,517 new infections were reported in the northern province of Kujawsko-Pomorskie.
The western province of Wielkopolskie, which is home to the major city of Poznań, had the third-highest number of new infections confirmed by officials on Thursday, at 1,469.
On November 7, the Polish health ministry confirmed 27,875 new single-day cases, the most since the pandemic hit the country in early March.
Meanwhile, 1,036,138 people have now recovered from COVID-19 throughout the country, including 10,249 over the last 24 hours, the health ministry also said.
Poland on Monday entered a three-week "national quarantine" as it struggles to contain the coronavirus.
Shopping malls have been ordered to close until January 17, though some retail outlets, such as grocery stores and pharmacies, are allowed to stay open.
Hotels and ski slopes will be shut to the general public throughout that period, and anyone arriving in Poland by public transportation will have to undergo a 10-day quarantine.
The new set of curbs comes after tougher measures to battle COVID-19 took effect across Poland last month following a surge in cases amid a second wave of the pandemic.
As part of those restrictions, theatres, cinemas, museums, galleries and gyms were told to close temporarily.
Meanwhile, schools and universities throughout the country have returned to distance learning.
Under restrictions announced in October, children under 16 are only allowed to leave their homes under the supervision of an adult between 8 a.m. and 4 p.m.
Meanwhile, pubs, restaurants and cafes are only allowed to provide take-aways and delivery orders.
Gatherings of more than five people have been forbidden, though people who live or work together are exempt from the rule.
