TL;DR: It is shown that early SARS-CoV-2 transmission in Connecticut was likely driven by domestic introductions, and the risk of domestic importation to Connecticut exceeded that of international importation by mid-March regardless of the estimated effects of federal travel restrictions.

TL;DR: The United Kingdom's COVID-19 epidemic during early 2020 was one of world's largest and was unusually well represented by virus genomic sampling as mentioned in this paper, which determined the fine-scale genetic lineage structure of this epidemic through analysis of 50,887 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genomes, including 26,181 from the UK sampled throughout the country's first wave of infection.

TL;DR: Because significant spread has already occurred, a large number of airline travellers may be required to be screened at origin high-risk cities in China and destinations across the globe for the following three months of February to April, 2020 to effectively limit spread beyond its current extent.

TL;DR: The fine-scale genetic lineage structure of this epidemic is revealed through analysis of 50,887 SARS-CoV-2 genomes, including 26,181 from the UK sampled throughout the country's first wave of infection.

TL;DR: The number of imported SARS-CoV-2 cases is on the rise in Brazil, and incidence and historical air travel data are used to estimate the most important routes of importation into the country.
