TL;DR: Based on individual records of 1178 potential SARS-CoV-2 infectors and their 15,648 contacts in Hunan, China, the authors estimated key transmission parameters.

TL;DR: The novel coronavirus disease 2019 (COVID-19) was first reported in Wuhan, China, where the initial wave of intense community transmissions was cut short by interventions and had a higher burden than the 2009 influenza pandemic or seasonal influenza in terms of hospitalization and mortality rates.

TL;DR: These findings support the contribution of children to transmission and the importance of pre-symptomatic transmission, in turn highlighting the need for large-scale testing, contact tracing activities, and the use of personnel protective equipment during the COVID-19 pandemic.

TL;DR: The CFR estimates based on laboratory-confirmed cases ascertained in mainland China suggest that COVID-19 is more severe than the 2009 H1N1 influenza pandemic in hospitalized patients, particularly in Wuhan.

TL;DR: Wang et al. as discussed by the authors assessed the case fatality risk (CFR) of COVID-19 in mainland China, stratified by region and clinical category, and estimated key time-to-event intervals.
