China A news briefing related to the research into the source of the corona virus was held on 8 April. According to the preliminary research data uploaded by the Chinese Center for Disease Control on the Global Initiative of Sharing All Influenza Data platform, some international experts found different research results.
Professor Thong Yikang, head of the School of Life at Beijing University of Chemical Technology, said the Chinese Center for Disease Control uploaded preliminary research data found at the Huanan seafood market. The analysis of data using different methods, software and parameters can give different results. But analysis of the DNA barcodes in the data revealed that the hosts of the samples found in the environment are mostly human. This indicated that the virus found in the environment of the Huanan Seafood Market may have been acquired from the patient.
At the same time, it is clear from the analysis of DNA barcode that before the closure of Huanan Seafood Market, animals like pig, sheep, chicken and duck are also present in the market. Some experts have expressed apprehension that these animals may have given the virus to people in the market, but the data so far shows that there is no symptom of virus infection in animals in the market. That’s why the above estimate is not scientific.
