The Russian Satellite News Agency reported on the 26th that researchers at the Affiliated Hospital of Axchus University in Norway found that the emergence of antibodies to the new coronavirus can be traced back to December 2019, which is one month earlier than the first confirmed case announced in Europe.
Researchers at Axchus University have reportedly found antibodies to the new coronavirus in an anonymously stored blood sample. The samples were taken from pregnant women in the first trimester of pregnancy and, as part of maternal care, were stored to monitor for potential infectious diseases. Of the 6520 samples, 98 detected antibodies to the virus. Eskid, the project's director, noted that there were many indications that they had been infected abroad.
Eskid said the discovery was "very surprising" and could change the history of the coronavirus pandemic in Norway and the world. The coronavirus may spread widely in most parts of the world sooner than expected. He said few countries can store enough blood samples, so there are few other retrospective studies.
According to Norwegian officials, the first case of COVID-19 in Europe occurred on 27 January 2020, and the virus spread to Norway on 24 February 2020. The results of a November 2020 study by the National Cancer Institute in Milan, Italy, showed that antibodies to the new coronavirus had been detected in blood samples taken from residents in September 2019.
