The newly emergent human virus SARS-CoV-2 (severe acute respiratory syndrome-coronavirus 2) is resulting in high fatality rates and incapacitated health systems. Preventing further transmission is a priority. We analyzed key parameters of epidemic spread to estimate the contribution of different transmission routes and determine requirements for case isolation and contact tracing needed to stop the epidemic. ⋯ A contact-tracing app that builds a memory of proximity contacts and immediately notifies contacts of positive cases can achieve epidemic control if used by enough people. By targeting recommendations to only those at risk, epidemics could be contained without resorting to mass quarantines ("lockdowns") that are harmful to society. We discuss the ethical requirements for an intervention of this kind.

What Caused the Outbreak of COVID-19 in China: From the Perspective of Crisis Management.
Since the first known case of a COVID-19 infected patient in Wuhan, China on 8 December 2019, COVID-19 has spread to more than 200 countries, causing a worldwide public health crisis. The existing literature fails to examine what caused this sudden outbreak from a crisis management perspective. This article attempts to fill this research gap through analysis of big data, officially released information and other social media sources to understand the root cause of the crisis as it relates to China's current management system and public health policy. ⋯ Finally, the privatization of many state-owned hospitals led to the unavailability of public health medical resources to serve affected patients in the Wuhan and Hubei Province. This article suggests that China should adopt a Singaporean-style public health crisis information management system to ensure information disclosure and information symmetry and should use it to monitor public health crises in real time. In addition, the central government should adopt the territorial administration model of a public health crisis and increase investment in public health in China.

Since its origin in China, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has become a pandemic and spread to 209 countries. As coronavirus disease 2019 (COVID-19) is a very rapidly emerging disease, organ-specific studies related to it have been reported. Apart from respiratory findings, some studies have highlighted inflammatory consequences in the heart, kidney, and/or liver as well. ⋯ Nevertheless, the mechanism of heart injury in COVID-19 is not clear yet. However, multiple studies that highlight the clinical features, laboratory findings, and prognosis of acute myocardial injury (AMI) in COVID-19-affected individuals have been published. In this review, we have summarized the findings of all those studies as well as the clinical features and management of cardiac injury discussed by some case reports.
