<div>Overall, there are limited data regarding the aerosolization and transmission risk of SARS-CoV-2 during endoscopic procedures of the aerodigestive tract for COVID positive patients. Aggregate data from a variety of aerosol generating procedures revealed fewer infections among health care workers who used eye protection (38 of 599 [6.3%]) or respirators (4 of 95 [4.2%]) compared to those who used surgical mask (82 of 266 [30.8%]), gown (124 of 864 [14.4%]), or gloves (122 of 994 [12.3%]). Given the limited data, further research in this area is warranted.</div>
