Abstract:
This commentary describes some of the aspects of the COVID-19 pandemic in Poland. The 1st part of the text covers issues related to actions introduced by the Polish government to minimize the risk of infection as well as statistics and difficulties resulting from the restrictions introduced. In the 2nd part, we present the results of our own research, including predictors of posttraumatic stress disorder symptom severity associated with the pandemic situation, and we discuss the results.
