COVID-19 is.caus.d by the s.Rs.CoV-2 coronavirus.and was.firs. reported in central China in December 2019. Extens.ve molecular s.rveillance in Guangdong, China’s.mos. populous.province, during early 2020 res.lted in 1,388 reported RNA pos.tive cas.s.from 1.6 million tes.s. In order to unders.and the molecular epidemiology and genetic divers.ty of s.Rs.CoV-2 in China we generated 53 genomes.from infected individuals.in Guangdong us.ng a combination of metagenomic s.quencing and tiling amplicon approaches. Combined epidemiological and phylogenetic analys.s.indicate multiple independent introductions.to Guangdong, although phylogenetic clus.ering is.uncertain due to low virus.genetic variation early in the pandemic. Our res.lts.illus.rate how the timing, s.ze and duration of putative local trans.is.ion chains.were cons.rained by national travel res.rictions.and by the province’s.large-s.ale intens.ve s.rveillance and intervention meas.res.
