In December, 2019, an outbreak of the novel coronavirus (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) occurred in Wuhan, China, and soon spread all over the world. Rapid and accurate diagnosis of SARS-CoV-2 infection is the cornerstone of all efforts to stem its advancement.
The detailed report by Timothy Harkin and colleagues of an unusual case of respiratory illness eventually diagnosed as COVID-19 raises issues about the role of imaging in the management of the disease. The causative virus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can result in lethal pneumonia, so might chest imaging have a central role in the detection or management of COVID-19? Is there a signature imaging appearance of the virus that could alert radiologists to its presence?
The novel coronavirus disease 2019 (COVID-19), caused by the pathogen severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), originated in Wuhan, China, and has now spread internationally with over 4·3 million individuals infected and over 297 000 deaths as of May 14, 2020, according to the Johns Hopkins Coronavirus Resource Center.
It is urgent to understand the future of severe acute respiratory syndrome–coronavirus 2 (SARS-CoV-2) transmission. We used estimates of seasonality, immunity, and cross-immunity for betacoronaviruses OC43 and HKU1 from time series data from the USA to inform a model of SARS-CoV-2 transmission.
The ongoing coronavirus disease 2019 (COVID-19) outbreak expanded rapidly throughout China. Major behavioral, clinical, and state interventions were undertaken to mitigate the epidemic and prevent the persistence of the virus in human populations in China and worldwide. It remains unclear how these unprecedented interventions, including travel restrictions, affected COVID-19 spread in China.
Estimation of the prevalence and contagiousness of undocumented novel coronavirus (SARS-CoV2) infections is critical for understanding the overall prevalence and pandemic potential of this disease.
A estimativa da prevalência e contagiosidade de novas infecções por coronavírus não documentadas [síndrome respiratória aguda grave - coronavírus 2 (SARS-CoV-2)] é fundamental para entender a prevalência geral e o potencial pandêmico dessa doença.

El 30 de enero de 2020, la OMS declaró que el brote de COVID-19 constituía una emergencia de salud pública de importancia internacional. Inicialmente, la mayoría de los casos se notificaron en China y en personas que habían viajado a China. La situación más reciente puede consultarse en los informes de situación sobre la COVID-19 (en inglés).
