Resumen
GB is a recipient of CNPq fellowship for Productivity in technological
Development and Innovative Extension (Grant 302317/2017-1) and is funded by grant from
FAPERJ (Grant E-26/202.896/2018). D.M is member of the Sistema Nacional de Investigadores
(National Research System- SNI-ANII, UY). The SARS-CoV-2 rapidly spread around the world during 2020, but the precise time in which the virus began to spread locally is currently unknown for most countries. Here, we estimate the probable onset date of the community spread of SARS-CoV-2 from the cumulative number of deaths reported during the early stage of the epidemic in Western Europe and the Americas. Our results support that SARS-CoV-2 probably started to spread locally in all western countries analyzed between the middle of January and early February 2020, thus long before community transmission was officially recognized and control measures were implemented.
