Sasin, who also serves as Minister of State Assets, is “being cared for by doctors in hospital," Karol Manys, a spokesman for the ministry, told state news agency PAP.
Manys said last Thursday that Sasin had been infected with the coronavirus.
Among high-profile Polish politicians who have contracted COVID-19 is President Andrzej Duda, who tested positive in October. Duda later said he was in good health.
Sasin, meanwhile, has been in quarantine several times previously, according to the PAP agency.
