Geographic reconstruction of the SARS-CoV-2 outbreak in Lombardy (Italy) during the early phase	2020-07-24		.txt	text/plain	2400	149	51	The circulation of SARS-CoV-2 in Italy has been dominated by two large clusters of outbreaks in Northern part of the peninsula, source of alarming and prolonged infections in Lombardy region, in Codogno and Bergamo areas especially. The molecular clock analysis estimated a clusters divergence approximately one month before the first patient identification, supporting the hypothesis that different SARS-CoV-2 strains spread all over the world at different time, but their presence became evident only in late February along with Italian epidemic emergence. A dataset of 41 genome assemblies of Sars-Cov-2 strains isolated in Italy between 20 February 2020 and 30 March 2020 were retrieved from GISAID database 12 , (see Supplementary Table 1 for details). All patients were resident in Lombardy Region, distributed in different provinces, as reported in table X: in particular, the category 'Milano' contains also patients hospitalized for non-COVID-19 disease, for whom SARS-CoV-2 hospital acquisition was supposed; in addition, HSacco-20, in 'Other' category, was a nurse living in Bergamo and working at Lodi Hospital.	./cache/cord-287101-k3zq75zc.txt	./txt/cord-287101-k3zq75zc.txt
