The Czech Health Ministry will wait to update its PES epidemic risk-and-alert system due to the British mutation of COVID and overburdened hospitals, Minister Jan Blatný said. The revised system, which included the introduction of a negative antigen test for people to attend mass events, was originally to take effect on Feb. 1. "At present, it cannot be softened because it is not clear how fast the British mutation will spread, and hospital capacities remain overburdened. I think it would be irresponsible to present the [modified] PES system and arouse people's hope without setting any relevant date," Blatný said, adding that the new system would enable people to live permanently with COVID and permit some activities the current system has ruled out. The opposition has criticized the ministry for keeping restrictions at the fifth, highest level despite the fact that the country has remained at the fourth, second-highest degree since Jan. 14.
