Selected aspects of mortality in Czechia and Slovakia in the pandemic year 2020.

The study identified a significant reduction in life expectancy at birth for both men and women in Czechia and Slovakia between 2019 and 2020. The main reason for this phenomenon was the increase in mortality rates at senior ages, up to around age 90. However, the increase in mortality did not affect all age groups, but contributions at younger ages could not significantly compensate for the negative impact of older ages. The study confirmed mortality from COVID-19 as a major factor in declining life expectancy at birth but also noted a non-negligible effect of the worsened mortality rates from circulatory diseases. The negative impact of both groups of causes of death was particularly pronounced at the age of 65 and over.
