claim: genomic epidemiology of superspreading events in austria reveals mutational dynamics and transmission properties of sars-cov-2
evidence_1: phylogenetic clusters were identified on the basis of characteristic mutation profiles in viral genome sequences of sars-cov-2positive cases in austria.", "in this study, we reconstructed major sars-cov-2 infection clusters in austria and analyzed their role in international virus spread by combining phylogenetic and epidemiological analyses.")
