Chinanews.com, November 1st. According to Euronet, citing EUN News Agency, researchers from the University of Basel in Spain, the Federal Institute of Technology Zurich in Switzerland, and the Spanish Council for Advanced Research found that researchers from the University of Basel in Spain, the Swiss Federal Institute of Technology in Zurich, and the Spanish Council for Higher Research The strain can be traced back to Spain.

Researchers have named the strain "20A.EU1".

  According to reports, the researchers of the research team found that after the second wave of the new crown epidemic on the European continent, 80% of the infected people in Spain have the 20A.EU1 strain, and the proportion of the infected people in the United Kingdom is as high as 90%. , Iceland accounts for 60%, and Switzerland has 30-40% of infected people containing the strain.

France, Germany, the Netherlands, Latvia, Italy, Belgium, Sweden, Norway and other countries also found that a large number of infected people contained the strain.

  Professor Emma Hodcroft, a Swiss evolutionary geneticist who participated in the project, said that by analyzing a large number of new coronavirus genomes, the researchers traced another variant of the new coronavirus 20A.EU1 strain and found it Originated in northeastern Spain, especially in Catalonia.

  Regarding the source and super spreader of 20A.EU1, researchers believe that this strain was first discovered in agricultural workers in Catalonia and Aragon, Spain, and then spread rapidly in the local area and spread through tourists. To other European countries.

  Studies have confirmed that the 20A.EU1 virus strain has appeared in Spain since June, and the transmission rate in Spain in July has exceeded 40%; in September, the transmission rate in Switzerland, Ireland and the United Kingdom reached 40-70%, and spread to at least 12 in Europe country.

  The researchers pointed out that there is currently no evidence that this variant of the new coronavirus strain is more infectious or lethal.

In the second wave of epidemics in Europe, the Spanish new crown epidemic rebounded significantly earlier than other European countries, and it basically coincided with the time when Spain resumed travel, which also confirmed the statement that the 20A.EU1 strain originated in Spain.
