摘要

The novel severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has resulted in coronavirus disease 2019(COVID-19)which has affected more than 4.5 million people in 213 countries,and has been declared a pandemic by World Health Organization on March 11,2020.The transmission of SARS-CoV-2 has been reported to occur primarily through direct contact or droplets.There have also been reports that SARS-CoV-2 can be detected in biopsy and stool specimens,and it has been postulated that there is potential for fecal–oral transmission as well.Gastrointestinal symptoms have been reported in 17.6%of COVID-19 patients and transmission can potentially occur through gastrointestinal secretions in this group of patients.Furthermore,transmission can also occur in asymptomatic carriers or patients with viral shedding during the incubation period.Endoscopic procedures hence may pose significant risks of transmission(even for those not directly involving confirmed COVID-19 cases)as endoscopists and endoscopy staff are in close contact with patients during these aerosol generating procedures.This could result in inadvertent transmission of infection at time of endoscopy.
