The Robert Koch Institute (RKI) gives the nationwide seven-day incidence on Tuesday morning at 522.7.

This is evident from numbers that reflect the status of the RKI dashboard at 5 a.m.

The day before, the value of new infections per 100,000 inhabitants and week was 499.2 (previous week: 632.3 previous month: 1097.9).

However, the incidence does not provide a complete picture of the infection situation.

Experts have been assuming for some time that there will be a large number of cases not recorded by the RKI - due to overworked health authorities and because not all infected people have a PCR test done.

Only these count in the statistics.

In addition, late registrations or transmission problems can lead to a distortion of individual daily values.

The health authorities in Germany recently reported 107,568 new corona infections (previous week: 113,522 registered infections) and 218 deaths (previous week: 240) to the RKI within one day.

Here, too, comparisons of the data are only possible to a limited extent due to the test behavior, late registrations or transmission problems.

In general, the number of registered new infections and deaths varies significantly from weekday to weekday, since more and more federal states do not transmit to the RKI, especially at weekends, and report their cases later in the week.

The RKI has counted 25,406,868 detected 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.

Corona endemic in 2023?

The infectiologist Marylyn Addo expects that Germany will reintroduce the mask requirement in winter: “We will have a good summer.

The number of cases will increase again in autumn.

I assume that measures such as the obligation to wear masks will come back in winter - at least in public spaces and indoors where it is difficult to keep your distance," Addo told the Rheinische Post in Düsseldorf.

But she does not expect new lockdowns: "I do not expect lockdowns at the moment because of the growing immunity." Many people are vaccinated, even if not enough.

Addo further emphasized: “The corona virus will be with us for years to come, but it could become endemic in 2023.

The scenario could then look like this: As with influenza, the numbers go up in winter, risk groups have to protect themselves.

Otherwise, hygiene, ventilation and keeping your distance help.”

She expects that many vaccine candidates will no longer come onto the market, which Biontech and Moderna dominate: “There are still 196 vaccine candidates in preclinical studies and 117 in clinical studies.

Only a small fraction of this will come onto the market,” adds Addo.

Addo is a professor at the University Hospital Hamburg-Eppendorf (UKE).
