Despite the progressive spread of the pandemic throughout the national territory, its impact continues to be characterised by high regional heterogeneity, particularly when taking into account, in addition to the absolute numbers of confirmed cases and deaths, relative indicators according to the size and population density per km2 of the territorial units considered in this analysis. Taking the municipality as a reference unit and data available for April 22 (2 weeks more than in the previous press release on the same topic), it can be seen that:
• On April 22, 2020, in Portugal, for every 10,000 inhabitants there were 21.7 confirmed cases of COVID-19. The number of confirmed cases of COVID-19 disease per 10 thousand inhabitants was above the national value in 47 municipalities and of this group, 33 belonged to the Norte region.
• The analysis of the relationship between the number of confirmed cases per 10 thousand inhabitants and population density highlights a set of 32 municipalities with values above the national average in both indicators.
