Poland recorded 418 new Covid-19 cases the health ministry said on Thursday, the highest daily rise in more than a month and up from 380 on Wednesday. Nine new deaths takes the country's total to 1,651.

The number of active cases, which has fallen steadily from a high of 14,665 on June 19, has started rising again in recent days, and was up to 8,388 on Thursday.

Of the new cases, 110 were recorded in Upper Silesia, while 104 were in Mazowsze, home to the capital Warsaw.
The spike in cases in Mazowsze may be due to an outbreak following a wedding.

Upper Silesia is where most of Poland’s coal mines are located, three of which have seen outbreaks this week. Coal miners account for 16% of all cases in Poland, although around 97% of those infected are asymptomatic, according to the health ministry.
