The virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces, according to a new study from National Institutes of Health, CDC, UCLA and Princeton University scientists in The New England Journal of Medicine. The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on...

OBJECTIVE To investigate the relationship between the ABO blood group and the COVID-19 susceptibility. 
DESIGNThe study was conducted by comparing the blood group distribution in 2,173 patients with COVID-19 confirmed by SARS-CoV-2 test from three hospitals in Wuhan and Shenzhen, China with that in normal people from the corresponding regions. Data were analyzed using one-way ANOVA and 2-tailed χ 2 and a meta-analysis was performed by random effects models. SETTING Three tertiary...

Background Chloroquine and hydroxychloroquine have been found to be efficient on SARS-CoV-2, and reported to be efficient in Chinese COV-19 patients. We evaluate the role of hydroxychloroquine on respiratory viral loads. 
Patients and methods Patients were included in a single arm protocol to receive 600mg of hydroxychloroquine daily and their viral load in nasal swabs was tested daily. Depending on their clinical presentation, azithromycin was added to the treatment. Untreated patient...

This is the second edition (version 1.2) of this document, which was originally adapted from Clinical management of severe acute respiratory infection when MERS-CoV infection is suspected (WHO, 2019). 
It is intended for clinicians involved in the care of adult, pregnant, and paediatric patients with or at risk for severe acute respiratory infection (SARI) when infection with the COVID-19 virus is suspected. Considerations for paediatric patients and pregnant women are highlighted throu...

Since the novel coronavirus (SARS-CoV-2) was identified in Wuhan, China, at the end of 2019, the virus has spread to 32 countries, infecting more than 80000 people and causing over 2600 deaths globally. The viral infection causes a series of respiratory illness including severe respiratory syndrome, indicating the virus most likely infects respiratory epithelial cells and spreads mainly via respiratory tract from human to human. However, viral target cells and organs haven’t been fully ...

Recommendations for GI endoscopy and clinic practices:
Strongly consider rescheduling elective non-urgent endoscopic procedures. Some non-urgent procedures are higher priority and may need to be performed (examples include cancer evaluations, prosthetic removals, evaluation of significant symptoms). Classification of procedures into non-urgent/postpone and non-urgent/perform may be useful. Of note, the Surgeon General on 3/14/20 advised hospitals to postpone all elective surgeries5...

SAGES is committed to the protection and care of patients, their surgeons and staff, and all who are served by the medical community at large. Through this prism, the following recommendations are made in light of the COVID-19 pandemic.
1. All elective surgical and endoscopic cases should be postponed at the current time. There are different levels of urgency related to patient needs, and judgment is required to discern between these. However, with the numbers of COVID-19 patients ...
