Abstract

Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although, respiratory symptoms are typical the digestive system is also a susceptible target with gastrointestinal symptoms present even in the absence of respiratory symptoms. The gastrointestinal symptoms of COVID-19 include diarrhea, abdominal pain, anorexia, and nausea among other symptoms. Some questions that remain to be answered include: Do patients with gastrointestinal symptoms have a higher mortality? SARS-CoV-2 variants are already a global reality: Do these variants present with a greater prevalence of gastrointestinal symptoms? Do patients with these symptoms warrant more intensive care unit care?</p>
