- [pre-print, not peer reviewed] Contrary to earlier conclusions, based on phylogenetic analysis, Worobey et al. conclude that the first SARS-CoV-2 case identified in Washington State in January 2020 was not linked to outbreaks that occurred weeks later. Rather, the subsequent outbreak was due to a separate later importation from China. The authors speculate that the rapid public health response may have prevented an earlier outbreak.
