종합적인 역학조사와 빅데이터 분석을 결합, 연구원들은 베이징 신파디 시장에 전염병이 집중된 상황에서 바이러스 출처가 해외 전염병 지역의 저온 유통 수입 식품일 가능성이 매우 높다는 것을 밝혔습니다., 저온 유통 운송이 SARS-CoV-2를 확산시키는 새로운 방법이 될 수 있다고 제안했습니다..
6월 11, 2020, 갑자기 나타난 SARS-CoV-2 감염 사례, 베이징에서 새로운 사건이 발생하지 않는 평온함을 깨뜨림 56 연속 일. 환자는 즉시 병원으로 이송됐다, 그리고 그의 상태는 빠르게 통제되었습니다, 그런데 어디서 바이러스에 감염됐는지 미스터리가 됐다..
The chilled salmon is the only product from overseas in the goods sold at booth S14. 그러므로, 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.
10월에 23, Tsinghua University, Beijing Municipal Center for Disease Control and Prevention, Institute of Pathogenic Biology, Chinese Academy of Medical Sciences, Peking University and Beijing Genomics Institute of Chinese Academy of Sciences jointly published a document in National Science Review. By analyzing the nucleic acid sequencing and virus genome sequence of related cases, environment and food samples, combined with comprehensive epidemiological investigation and big data analysis, the researchers revealed that the source of the virus in the epidemic is very likely to be cold chain imported food in overseas epidemic areas, and proposed that cold chain transportation may be a New way of communication in SARS-CoV-2.For reference, the cold chain is the source. It seems that the situation of Wuhan South China seafood market may also be in this respect. It seems that the input problem is clearer.
