In the corona pandemic in Germany, the omicron subline BA.5 is now predominant.
In its weekly report on Covid-19 on Thursday evening, the Robert Koch Institute (RKI) speaks of a share of around 50 percent.
However, this data refers to the week before last.
Higher values can currently be assumed.
The RKI also recorded a further increase in the seven-day incidence of 23 percent and a slightly increasing burden on the health care system.
This applies in particular to intensive care medicine, it said.
The age group of 70 to 79 year olds is particularly affected by the infections at 32 percent.
The report goes on to say: "The number of outbreaks in old people's and nursing homes and in medical treatment facilities has increased compared to the previous week."
As can be seen from the Divi intensive care register, the number of people infected with corona treated there has been increasing again for a few days: after a good 600 patients at the beginning of the month, it was 810 as of Thursday. However, the number of newly hospitalized patients with severe infections remains low Level.
Fully vaccinated would still have a very low risk of severe Covid 19 disease.
According to the RKI report, the variant BA.5 had had a share of 32 percent the week before.
"The shares of the sub-lines BA.2.12.1 and BA.4 each increased to six percent," write the experts.
In view of the rising incidences due to the more widespread use of BA.4 and BA.5, the RKI continues to call for compliance with the recommendations for avoiding infection.
Not every positive sample is examined for the sub-lines, only a random sample.
