According to the Robert Koch Institute (RKI), the omicron sublines, which have been increasing proportionally for a few weeks, are already dominant.

“The strong growth of BA.4 and BA.5 in particular, but also BA.2.12.1, suggests that these variants currently already make up the majority of the evidence,” says the RKI weekly report on Sars-CoV-2 from Thursday evening. It is based on evaluations of virus variants.

This data in the report always refers to the week before last: BA.5 made up around 24 percent of the positive samples in a random sample at the time, which again corresponds to around a doubling of the value from the previous week. BA.4 and BA.2.12.1 were both around four percent.

Because of the greater spread compared to the previously dominant pathogens, these variants could contribute to a renewed increase in the number of infections, it said.

In the development of the seven-day incidence, the RKI speaks of a significant increase of around one third for the past week compared to the previous week. All age groups are affected. More outbreaks in old people’s and nursing homes and in medical treatment facilities have also been recorded again.
