WARSAW, July 31 (Reuters) - The Polish government will consider new restrictions for certain parts of Poland with the most new coronavirus cases, a government official said on Friday, after the number of new cases rose by a record amount for the second successive day.
The Health Ministry reported 657 new cases and seven deaths, taking the total number of cases since the pandemic began to 45,688 and the death toll to 1,716.
Poland has reported fewer cases of COVID-19 than some other European countries, but the number of new infections is now climbing. While a crisis meeting was held on Friday, no new immediate measures were announced.
"Limits could cover certain counties, the ones that have the biggest problems when it comes to a rise in infections," Poland's government spokesman Piotr Muller told a press conference on Friday, without specifying the areas.
Of the new cases, 227 were in the Silesia region, where there has been an outbreak among coal miners.
Muller also said that restrictions would unlikely be nationwide and that the government would explore imposing quarantine measures on travellers from certain countries also facing a rapid growth in new cases.
High numbers of new cases are expected over the coming days, a spokesman for the Health Ministry told state news agency PAP, drawing attention to the situation in Silesia.
