The Robert Koch Institute (RKI) gave the nationwide seven-day incidence on Thursday morning as 462.4. This is evident from numbers that reflect the status of the RKI dashboard at 5 a.m. The day before, the value of new corona infections per 100,000 inhabitants and week was 414.0 (previous week: 409.9; previous month: 219.1). However, this information only provides a very incomplete picture of the number of infections. Experts have been assuming for some time that there will be a large number of cases not recorded by the RKI - mainly because by far not all infected people have a PCR test done. Only positive PCR tests count in the statistics. In addition, late registrations or transmission problems can lead to a distortion of individual daily values.
The RKI has counted 33,652,255 infections with Sars-CoV-2 since the beginning of the pandemic. The actual total number is likely to be significantly higher, as many infections go undetected.
