Spatial variability of SARS-CoV-2 infection in the Silesian voivodeship, Poland.

Introduction: SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) and related to infection COVID-19 (coronavirus disease 2019) remain a new and global challenge for public health. Due to the location, specifics of employment, and the high density of population in the Silesia voivodeship it is appropriate to study the available epidemiological data in a region with a potentially higher risk of infection.

Material And Methods: In the descriptive model of the study, data on the number of infected, hospitalized, and dead people due to SARS-CoV-2 infection were analyzed. The source of information was daily reports conducted by the Provincial Sanitary and Epidemiological Station in Katowice, in the period from March 5 to August 18, 2020.

Results: Results of antigenic molecular tests for SARS-CoV-2 infection in the Silesian voivodeship indicate that in the first half of 2020, the infection rate was approximately 5% and the symptomatic form of the disease was approximately 20%.

Conclusions: The analysis of the frequency of infection and mortality in the poviats reveals a large variation in the occurrence of both phenomena, but the explanation of this difference is not possible due to the descriptive nature of the analysis and the secondary form of epidemiological data.
