Another 1,911 COVID cases were reported on Sunday, 169 more than a week ago, which was the first week-on-week rise since March 12, according to the latest data from the Czech Health Ministry. Since the outbreak last March, the epidemic has claimed 27,057 lives. Most of the deaths occurred this year. The value of the PES system, which guided the lockdown in the Czech Republic previously, rose to 55 by today. In the previous two days, it was three points lower on the 0-100 scale. The change was due to the rise in the reproduction number, which represents the number of people infected by one positive person, from 0.76 to 0.81. The value of the PES still corresponds with the third out of the five degrees of epidemic risk. However, the epidemic measures still reflect the fifth, strictest degree of alert. On Sunday, doctors applied 10,208 doses of Covid vaccines, 700 more than a week ago. Some 1.8 million Czechs have received at least one dose of the vaccine and 576,328 have both.
