In February and March 2020, health authorities in Poland carried out laboratory testing of suspected cases of infection by SARS-CoV-2, one of the seven known human coronaviruses, as well as home quarantining and monitoring.

As of 30 October 2020, a total of 340,834 confirmed SARS-CoV-2 cases, 134,724 recoveries, and 5,351.

On 24 March, Poland’s government announced further restrictions on people leaving their homes and on public gatherings to further limit the spread of SARS-CoV-2 infections. The new limits constrained gatherings by default to a maximum of two people (with an exception for families); an exception for religious gatherings, such as mass in the Catholic Church, funerals and marriages in which five participants and the person conducting the ceremony were allowed to gather; and an exception for work places.

Non-essential travel was prohibited, with the exception of travelling to work or home, SARS-CoV-2 control related activities, or “necessary everyday activities”.  The restrictions were initially defined for the period from 25 March to 11 April inclusive.As of 12 March 2020, the National Bank of Poland, to which commercial banks in Poland send their bank notes to, carried out a two-week quarantine procedure and heating at 150 °C (302 °F) for all bank notes, prior to returning the notes for circulation.

According to the regulation, minors (aged under 18) were prohibited from leaving their homes unaccompanied by a legal guardian. Parks, boulevards and beaches were closed, as well as all hairdressers, beauty parlours and tattoo and piercing salons. Hotels were allowed to operate only if they had residents in quarantine, in another form of isolation, on an obligatory work delegation for services such as building construction or medical purposes.

The gatherings were allowed to be bigger, up to 50 people, inclusive of religious personnel, to start from 12 April 2020 until further notice. An updated regulation on 10 April retained the authorisation of religious/funeral gatherings of up to 50 people but shifted the start date to 20 April (Article 9.2) while other gatherings remained banned (Article 14) 1 person per 10 m2.On 9 April, Mateusz Morawiecki announced that the closure of educational institutions and international transport would continue to 26 April, the borders would remain “closed” until 3 May, and people entering Poland would still be required to be quarantined for 14 days.
