Identifying Locations with Possible Undetected Imported Severe Acute Respiratory Syndrome Coronavirus 2 Cases by Using Importation Predictions.
Cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection exported from mainland China could lead to self-sustained outbreaks in other countries. By February 2020, several countries were reporting imported SARS-CoV-2 cases. ⋯ Our model can be adjusted to account for exportation of cases from other locations as the virus spreads and more information on importations and transmission becomes available. Early detection and appropriate control measures can reduce the risk for transmission in all locations.

In December 2019, coronavirus Disease 2019 (COVID-19) occurred in Wuhan, Hubei Province, China. The disease has rapidly spread from Wuhan to other regions. ⋯ The clinical symptoms, laboratory results and imaging reports of patients with COVID-19 in Hunan area are significantly different from those in Wuhan area. For non-Wuhan epidemic areas, more attention should be paid to nucleic acid test results of throat swabs and stools, and it is not easily to diagnose based on clinical symptoms and CT results. Reduced whole blood lymph count can be used as an adjuvant diagnosis of early SARS-CoV-2 infection. Attention should be paid to asymptomatic carriers, which is of great significance for the control of the global epidemic.

Coronavirus disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) has caused more than 6.1 million confirmed cases of COVID-19 in more than 188 countries, and has caused more than 370,000 deaths globally as of June 1, 2020. In addition, thousands of healthcare workers have also got infected with the virus. COVID-19 patients release large amounts of infectious viral particles in form of droplets from cough, sneeze and respiratory secretions. ⋯ As a result, during the current pandemic, most routine surgeries all around the world have been suspended, and only emergency surgeries are being performed. Facial trauma surgery is one such emergency surgery that cannot be delayed or suspended even in this pandemic. This review focuses on precautions surgeons have to take while managing facial trauma patients in the emergency department and while performing emergency surgeries on these patients during the current COVID-19 pandemic.

Comparative Study
A combined oropharyngeal/nares swab is a suitable alternative to nasopharyngeal swabs for the detection of SARS-CoV-2.
Given the global shortage of nasopharyngeal (NP) swabs typically used for respiratory virus detection, alternative collection methods were evaluated during the COVID-19 pandemic. This study showed that a combined oropharyngeal/nares swab is a suitable alternative to NP swabs for the detection of SARS-CoV-2, with sensitivities of 91.7% and 94.4%, respectively.

With emergence of pandemic COVID-19, rapid and accurate diagnostic testing is essential. This study compared laboratory-developed tests (LDTs) used for the detection of SARS-CoV-2 in Canadian hospital and public health laboratories, and some commercially available real-time RT-PCR assays. Overall, analytical sensitivities were equivalent between LDTs and most commercially available methods.
