Title: Haplotype networks of SARS-CoV-2 infections in the Diamond Princess cruise ship outbreak
  • Document date: 2020_3_27
    • ID: 7vuejy26_2
    Snippet: Here, we have generated a haplotype network of the SARS-CoV-2 outbreak using genome-wide single nucleotide variations (SNVs), identifying the genotypes of isolates that disseminated in the DP cruise ship after quarantine on Feb. 5. This study was approved by the research ethics committee of the National Institute of Infectious Diseases (approval no. 1091) 15 During the period from Feb. 15-17, we obtained the pharyngeal specimens of 896 persons (8.....
    Document: Here, we have generated a haplotype network of the SARS-CoV-2 outbreak using genome-wide single nucleotide variations (SNVs), identifying the genotypes of isolates that disseminated in the DP cruise ship after quarantine on Feb. 5. This study was approved by the research ethics committee of the National Institute of Infectious Diseases (approval no. 1091) 15 During the period from Feb. 15-17, we obtained the pharyngeal specimens of 896 persons (880 passengers, 15 crew members, and 1 quarantine officer). RT-qPCR testing for SARS-CoV-2 was positive for 148 individuals (138 passengers, 9 crew members, and 1 quarantine officer), indicating that the positivity rate was 16.4% (147 positive individuals [excluding the officer] / 895 subjects). This positivity rate was comparable to the rate determined after finishing PCR 20 testing for all persons (619 PCR positives for 3,711 persons, 16,6%; see report for more detail) (5).
