➤ Mobility researcher believes that the incidence of 35 is “unrealistic for the time being”

With the apparently rapid spread of a more contagious Corona mutant in Germany, the target of 35 in the seven-day incidence is moving from the perspective of experts. Without additional measures, reaching this value would appear “unrealistic for the time being”, explained the head of the department of traffic system planning and traffic telematics at the TU Berlin, Kai Nagel, of the German press agency. His group models the infection process in Berlin, among other things with anonymized cell phone data. According to Nagel, the results can be transferred to the situation nationwide.

 The  mutant B.1.1.7, which was first discovered in Great Britain before Christmas, is spreading, according to data from the Robert Koch Institute (RKI) from last week, in Germany: within two weeks, the proportion increased in random samples from just under 6 to 22 percent. If you take into account the significantly increased likelihood of infection, according to the model, the situation is “significantly more critical than we previously predicted,” explained Nagel. “If the current measures are simply retained, according to the model we will get a third wave; every type of opening enlarges this wave.”

Nagel emphasized: “We can counter this by generally avoiding indoor contact without protective measures.” Such contacts to be avoided included not only schools but also multi-person offices and mutual visits. Possible protective measures are masks, rapid tests, vaccinations and the relocation of events outside.


 The  models of the TU scientists also include key figures on the virus and aspects such as temperature and the leisure activities that depend on it. Most recently, no changes in people’s behavior could be seen in the mobility data, said Nagel – with the exception of the weekends, when more people were out and about when the weather was better. As long as these additional activities take place outdoors, “according to our models, however, they do not result in any relevant additional infections,” says Nagel.

RKI registers 3,883 new corona infections and 415 new deaths

 The  health authorities in Germany reported 3883 new corona infections to the Robert Koch Institute (RKI) within one day. In addition, 415 additional deaths were recorded within 24 hours. That comes from figures from the RKI on Tuesday. Exactly one week ago, the RKI had recorded 3856 new infections and 528 new deaths within one day.


 The  data reflect the status of the RKI dashboard from 3:11 a.m., subsequent changes or additions are possible.

According to the RKI, the number of new infections reported within seven days per 100,000 inhabitants (seven-day incidence) was 60.5 nationwide on Tuesday morning – and thus slightly lower than the previous day (61.0). Four weeks ago, on January 26, the incidence had been 107.6. Its previous high was reached on December 22nd at 197.6.


 The  high of 1,244 newly reported deaths was reached on January 14th. Among the new infections registered within 24 hours, the highest value was reached on December 18 with 33,777 – but it contained 3,500 late reports.


 The  RKI has counted 2,394,811 detected infections with SARS-CoV-2 in Germany since the beginning of the pandemic (as of February 23, 3:11 a.m.). ©

 The  actual total number is likely to be significantly higher since many infections are not detected. ©

 The  RKI stated the number of people recovered to be around 2,207,700. ©

 The  total number of people who died with or with a proven infection with SARS-CoV-2 rose to 68,318.

According to the RKI management report from Monday evening, the nationwide seven-day R-value was 1.05 (previous day 1.10). This means that 100 infected people theoretically infect 105 more people. ©

 The  value represents the occurrence of the infection 8 to 16 days ago. If it is below 1 for a long time, the infection process subsides.

Biden: More pandemic American deaths than both World Wars and Vietnam War combined

05:02 am: © The  USA passed the half a million corona death threshold on Monday. “This means that more Americans died in a single year because of this pandemic than in World War I, World War II and the Vietnam War combined,” said US President Joe Biden in a speech at the White House on Monday evening (local time).

On this sad occasion, it is time to commemorate the dead and to think of their relatives and friends. Biden ordered the lowering of the American flag to half-mast in order to commemorate the approximately 500,000 corona deaths in the country. This applies to public buildings, military bases and all US government diplomatic missions abroad, the White House said.

In his speech, Biden also warned strongly against dulling in view of the high number of deaths. “We have to fight against becoming deaf to suffering. We have to fight against seeing every life as a statistic,” said the 78-year-old. Every corona death had family, friends and an “extraordinary life” that ended too soon.

According to data from the University of Johns Hopkins, US authorities had reported 500,159 deaths after infection with the SARS-CoV-2 pathogen by Monday afternoon. In absolute numbers, there are no other country in the world that has so many confirmed corona deaths.

Biden wants to commemorate the victims of the pandemic in a speech on Monday evening (Tuesday, 12:00 a.m. CET). Afterwards, Biden and Vice President Kamala Harris want to keep a minute’s silence.

If there is at least three months between the first and second dose of AstraZeneca, the vaccine is more effective. This is the result of a study by the University of Oxford. ©
