[Pre-print, not peer-reviewed] Genome sequencing combined with epidemiological and mobility data suggest show that SARS-COV-2 was likely introduced in Louisiana from a single source via domestic travel and was being locally spread prior to the Mardi Gras celebrations in February 2020. However, further evidence suggests that Mardi Gras was likely a superspreading event, based on the unusual lack of genetic diversity of SARS-CoV-2, which was similar to cruise ship outbreaks, and the markedly increased infection rate in New Orleans immediately following the event.
