El nuevo virus de brote en Beijing proviene de alimentos importados de cadena fría

Combinado con investigación epidemiológica integral y análisis de big data, Los investigadores revelaron que la fuente de virus en la situación de epidemia concentrada en el mercado de Xinfadi en Beijing es muy probable que sean alimentos importados de cadena fría en áreas epidémicas extranjeras, y propuso que el transporte de la cadena fría puede ser una nueva forma para que SARS-Cov-2 se propague.

En junio 11, 2020, a case of SARS-CoV-2 infection suddenly appeared, breaking the calm of no new cases in Beijing for 56 dias consecutivos. The patient was admitted to hospital immediately, and his condition was quickly controlled, but it became a mystery where he was infected with the virus.

The chilled salmon is the only product from overseas in the goods sold at booth S14. Por lo tanto, the researchers sampled and tested the cold storage of all salmon suppliers in Xinfadi market, and found that five fish swab samples from a supplier were positive for SARS-CoV-2 nucleic acid, and the virus genome sequence obtained from sequencing of one unopened fish swab sample was highly homologous to the virus in human and environmental samples in this epidemic.
