The coronavirus epidemic also brought with it changes in the volume and structure of resources of the Czech health insurance system. Among the most significant are the two-phase increase in payments for state insured persons, shortfalls in health tax payments by employees and self-employed persons in connection with the reduction or cessation of their economic activity (including quarantine), and the drawdown of health insurers‘ reserves. The coronavirus disease by its nature falls within the scope of universally covered care and has significantly affected the situation of the Czech public health insurance. The aim of this paper is to examine and evaluate this development based on statistical data available as of the first half of 2021. Attention will be paid to the developments that have taken place, as well as to the more general implications for the sources of financing of the Czech public health insurance that arise from the resilience test that an epidemic of this magnitude undoubtedly represents.
