It has been more than 2 years since the outbreak of the novel coronavirus disease (COVID-19) pandemic in late 2019, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In an effort to minimize virus transmission, many endoscopic procedures were postponed in the beginning of the pandemic. However, recently, these procedures have resumed. During the pandemic, gastroenterologists worldwide have been attempting to develop and implement guidelines to prevent the spread of the virus during procedures [1-3]. Current evidence suggests that droplet transmission, aerosol transmission, and close contact with infected individuals are all plausible routes of SARS-CoV-2 transmission [4,5]. In other words, the virus can remain viable and infectious in aerosol for hours and on surfaces for several days [6], which may lead to nosocomial super-spreader events in endoscopy rooms. Endoscopy via oral routes, such as esophagogastroduodenoscopy, small bowel enteroscopy, endoscopic ultrasound, endoscopic retrograde cholangiopancreatography, breath tests, and esophageal manometry, is an aerosol-generating procedure [3,5]. Therefore, there has been an emphasis on the need for using personal protective equipment by healthcare professionals, including endoscopists [2,7]. Efforts have also been made to reduce virus transmission during endoscopy by using modified devices such as an endoscopic mouthpiece and a physical protective box [8,9].
