Robert Koch Institute: Incidence continues to rise

Status: 04/22/2022 07:13 a.m

According to the Robert Koch Institute, the nationwide seven-day incidence has risen to 733.4. 161,718 new infections were recorded within 24 hours. However, there should be late registrations among them.

The nationwide seven-day incidence has risen again compared to the previous day. The Robert Koch Institute (RKI) gave the value of new infections per 100,000 inhabitants per week as 733.4. For comparison: the day before the value was 720.6. A week ago, the nationwide incidence was 1001.5.

As the RKI further reported, citing data from the health authorities, the number of new infections reported within 24 hours was 161,718, after 186,325 the day before and 156,864 a week ago. In addition, 289 other deaths related to the corona virus were registered.

Numbers have to be put into perspective

The incidence values, which had fallen sharply in the past few days, were put into perspective by a note from the RKI. The institute pointed out that due to the Easter holidays and vacations, fewer tests were carried out and fewer cases of infection were recorded and transmitted than at other times. This means that “in the short term there may be an increased under-recording of cases in the reporting system”.

When looking at the values, it should also be taken into account that individual countries do not report data on every day of the week. This in turn leads to late registrations on the following days. A comparison of daily values ​​is therefore becoming increasingly difficult.

New sub-lines and mixed variants

In its weekly report, the RKI writes that several of the relatively new omicron sublines and mixed variants have so far been found relatively rarely or not at all in Germany. As of April 18, a total of 25 samples from line BA.5 had been detected. BA.4 has not yet been proven. In Germany, however, the genome is only decoded in a small proportion of the positive samples. The predominant subtype in Germany is currently BA.2, in the random sample the RKI states the proportion for the week before last at over 95 percent.

BA.4 and BA.5 have only recently become known and are classified as of concern by the World Health Organization (WHO) as part of Omicron. In addition, the RKI reports evidence of several mixed variants that are observed. They can develop when a host cell is infected with two different pathogens at the same time.
