The role of case importation in explaining differences in early SARS-CoV-2 transmission dynamics in Canada—A mathematical modeling study of surveillance dataBoth American and Canadian epidemics of coronavirus disease-2019 (COVID-19) are marked by stark geographic heterogeneities (Mishra et al., 2020). Despite reporting its first case on February 28, 2020—close to a month after Ontario on January 25th and British Columbia on January 28th—Quebec quickly became the epicenter of the Canadian COVID-19 epidemic. The disease’s mortality burden in that province, at 653 per million population, was 3.5 times as high as neighboring Ontario (186 per million) and 19 times that of British Columbia (at 35 per million) at the end of the first spring 2020 wave (Groupe de surveillance provinciale de la, 2020).
Adoption of personal protective measures by ordinary citizens during the COVID-19 outbreak in JapanThe coronavirus disease 2019 (COVID-19) outbreak has become a global problem (WHO, 2020b). As of March 23, 2020, the global number of reported cases of COVID-19 totaled approximately 330,000 cases, with 14,510 deaths (WHO, 2020c). Japan reported the first case of laboratory-confirmed COVID-19 on January 15, 2020, following confirmed cases in China and Thailand (WHO, 2020d). The number of patients is increasing daily.
