WARSAW, Poland (AP) — The official swearing-in of Poland's reshuffled government was postponed Monday and some members were put into quarantine after one of the ministers tested positive for COVID-19.

The ceremony conducted by President Andrzej Duda had been planned at the Presidential Palace for Monday afternoon, but the new education minister, Przemyslaw Czarnek, said early in the day he had a headache and a test showed he was infected with the coronavirus. He went into quarantine.

Prime Minister Mateusz Morawiecki asked that the swearing-in be postponed, and it didn't take place. No new date was immediately announced.

Spokesman Piotr Mueller said that health authorities ordered four other government members who have had contact with Czarnek to go into 10-day quarantine. Mueller said that for some time now government sessions have been held remotely and online.

Poland is seeing a high rise in the number of registered COVID-19 cases, with more than 2,000 new cases diagnosed each day in recent weeks.
