TL;DR: Patients with coronavirus disease 2019 (COVID-19) requiring treatment in an intensive care unit (ICU) in the Lombardy region of Italy were characterized, including data on clinical management, respiratory failure, and patient mortality.

TL;DR: The results suggest that early detection, hand washing, self-isolation, and household quarantine will likely be more effective than travel restrictions at mitigating this pandemic, and sustained 90% travel restrictions to and from mainland China only modestly affect the epidemic trajectory unless combined with a 50% or higher reduction of transmission in the community.

TL;DR: It is found that social distancing alone, as implemented in China during the outbreak, is sufficient to control COVID-19, and children 0 to 14 years of age are less susceptible to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

TL;DR: An agent-based model of SARS-CoV-2 transmission shows that testing, contact tracing and household quarantine could keep new COVID-19 waves under control while allowing the reopening of the economy with minimal social-distancing interventions.

TL;DR: The findings indicate that strict containment, movement restrictions, and increased awareness of the population have contributed to interrupt transmission of SARS-CoV-2 outside Hubei, and an early peak of infectiousness, with possible transmission before the onset of symptoms is suggested.
