The COVID-19 epidemic appeared in Poland in early March 2020 . Since then, the epidemic has impacted strongly on the socioeconomic nature of the country . Since April 2020, the region with the most confirmed cases is the province of Silesia (Śląskie). This paper has two main aims . First, the authors focus on explanations for the causes of the large number of confirmed cases in this region . The second issue is the mosaic pattern of COVID-19 cases in Śląskie province . The paper explains these patterns with reference to urban shrinkage, trans-industrialism, hard coal mining and polycentricity . The impact of these drivers is clearly visible in the local patterning of the pandemic . The authors point out that this specific relationship in this province complicates regional and local policy and indirectly affects state policy focused on the epidemic as well . The key problem is the negative impact of COVID-19 on hard coal mining . This sector, in turn, is considered by the Polish government as one of the most important from an economic and political point of view.
