The survey comprised questionnaires capturing emotional states, psychological disturbance, anxiety, and depression. The changes in the scores by time phase were studied for the whole sample and for gender and age groups. The results show that the threat of COVID-19 caused a significant increase in negative emotional experience and in the symptoms of psychological disturbance, anxiety, and depression in the Czech population in time of infection culmination, even when the spread of the pandemic was well controlled, and then a gradual decline over time.
