Mit der Verlängerung des Lockdowns soll vor allem die Verbreitung der Corona-Mutation verhindert werden ? das sei der falsche Ansatz, meint FDP-Vize Wolfgang Kubicki. Er wirft der Regierung Versagen vor und macht das an vier Punkten fest. (Video, 4:26 Min)

Corona-Mutationen sind ?kein Grund zur Panik"
Mutationen, die sich schneller verbreiten, seien bei einer Pandemie zu erwarten, sagte der Virologe Alexander Kekulé im Dlf. Es gebe aber keinen Grund, das zu dramatisieren. .....Nur wenn man hinschaut, findet man was. Ich persönlich vermute, dass wir weltweit wahrscheinlich noch eine Hand voll weiterer Varianten haben, die auf dem Vormarsch sind. Das heißt, die neuen Varianten werden kommen, aber es ist kein Grund jetzt zur Panik.

U.K. scientists initially thought it had a 50% higher mortality rate, but that turned out to be ?purely messy, biased data in the early days,? she says. ?I think that is a very strong reminder that we always have to be really careful with early data.? .....scientists say B.1.1.7 may already be much more widespread. Researchers in the Netherlands have found it in a sample from one patient taken in early December, Dutch health minister Hugo de Jonge wrote in a letter to Parliament today. They will try to find out how the patient became infected and whether there are related cases. Other countries may have the variant as well, says epidemiologist William Hanage of the Harvard T.H. Chan School of Public Health; the United Kingdom may have just picked it up first because it has the most sophisticated SARS-CoV-2 genomic monitoring in the world. Many countries have little or no sequencing......

auch die New York Times befasst sich mit B117

Through the process of natural selection, neutral or slightly beneficial mutations may be passed down from generation to generation, while harmful mutations are more likely to die out.A coronavirus variant first reported in Britain has 17 recent mutations that change or delete amino acids in viral proteins.
The variant was named Variant of Concern 202012/01 by Public Health England, and is part of the B.1.1.7 lineage of coronaviruses.Researchers are most concerned about the eight B.1.1.7 mutations that change the shape of the coronavirus spike, which the virus uses to attach to cells and slip inside....
Scientists suspect that one mutation, called N501Y, is very important in making B.1.1.7 coronaviruses more contagious.
Researchers think the N501Y mutation has evolved independently in many different coronavirus lineages. In addition to the B.1.1.7 lineage, it has been identified in variants from Australia, Brazil, Denmark, Japan, the Netherlands, South Africa, Wales, Illinois, Louisiana, Ohio and Texas.
In addition to N501Y, the B.1.1.7 has 16 other mutations that might benefit the virus in other ways. It?s also possible that they might be neutral mutations, which have no effect one way or the other. They may simply be passed down from generation to generation like old baggage.
.....One of the first mutations that raised concerns among scientists is known as D614G. It emerged in China early in the pandemic and may have helped the virus spread more easily. In many countries, the D614G lineage came to dominate the population of coronaviruses. B.1.1.7 descends from the D614G lineage.
