The first infected Swiss crown came from Ticino. The Federal Office of Public Health announced this on February 25. The man was previously in Italy, became infected there and took Corona to Switzerland. The virus spread like wildfire and Ticino became a fortress of the Crown.
So the course seems clear. But it is obviously not that simple. “There was no Swiss outbreak,” says ETH teacher Tanja Stadler in an online conference. That is the conclusion of a study that has not yet been published, as reported by the “Basler Zeitung”. Consequently, the virus has been in Switzerland for much longer than expected.
Together with her team, biomathematics analyzed more than 1,000 DNA samples from people infected with the Swiss crown. With the result: “The viruses were imported from various locations in Switzerland, and there is also no evidence of sources of infection in individual cantons.”
How does the virus change?
In addition to this knowledge, researchers are also trying to discover how the virus can change through mutations. Why it does For example, British scientists have examined and found the genome sequences of 5,300 Sars-Cov-2 viruses: The virus changes particularly frequently in two places. This also affects part of the key protein through which the coronavirus can enter the human body.
Other possible mutations could make the virus more dangerous or less dangerous to humans, allow it to have other routes of infection or carriers, or ensure that it can be infected multiple times. Therefore, it is crucial that scientists are always on the lookout for the virus. (ymh)
