The disease COVID-19 has been classified as pandemic by World Health Organisation (WHO) in March 2020. This poses a risk to healthcare workers. Whether esophagogastroduodenoscopy (EGD) is a aerosol-generating procedure (AGP) has brought controversy. Multiple international guidelines consider EGD as AGP based on expert consensus. No scientific data has been published regarding this. With a commercially available particle counter, we can differentiate the particle counts of different sizes in different areas of the endoscopy room. An increase from baseline particles of < 5um during or after the procedure would suggest that the procedure is an AGP. The baseline particle counts before and during the procedure are also recorded. The details of the procedure including procedure time and the use of sedation are also documented.
