How did the coronavirus spread in Europe last spring? Did the border closings in mid-March help? Researchers have an unequivocal answer.

Basel (dpa) –  The  border closings in Europe around a year ago came too late, according to a study, to stop the corona virus sustainably.

Researchers working with mathematician and biostatistician Tanja Stadler from ETH Zurich reported in the specialist magazine “PNAS” that there were already about as many local infections with the virus in Europe on March 8, 2020 as were brought in by travelers from abroad.

 The  EU only closed the borders on March 17th.

 The  researchers had traced the spread of the pathogen using sequenced virus genomes. “If you closed the borders with the aim of not letting the virus in: it was too late for that,” Stadler told the German press agency. In the event of an infection, as was already the case on March 8, a border closure would only make sense in connection with a drastic reduction in contacts in the country.

 The n the reduction in contacts from abroad will help to slow the spread.

Stadler and colleagues have examined the spread of Sars-CoV-2 in Europe using deciphered virus genomes from 19 European countries and the Hubei province in China. She works in the ETH Department of Biosystems, which is based in Basel.

From the processing, conclusions could be drawn for a possible new pandemic, said Stadler. “If it had been recognized earlier how dangerous the pandemic is, the source of infection would have had to be dried out. From an epidemiological point of view, an early foreclosure of the starting point of the pandemic in the Chinese province of Hubei would have been central, ”said the researcher. “It is extremely important to act quickly in the beginning to prevent a virus from circulating globally. But in retrospect you always know more. ”

In Germany, the first known chain of infection – after the infection of employees of the Webasto company in Upper Bavaria from a Chinese colleague – was interrupted at the end of January. This line is said to have expired and ended completely. But more infections were brought to Germany, from China and Italy, where the first major outbreak occurred in Europe.

In Italy, the local infections began around mid-February. “At the end of February, local circulation began in Germany,” said Stadler.

 The  virus variant, which was rampant in Europe until late spring, likely spread largely from Hubei through Italy.
