Research progress on the effect of COVID-19 on gastrointestinal tract

ABSTRACT

The outbreak of COVID-19 caused by severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) in 2019 threatens global public health. In the early stage, respiratory symptoms are the most common in patients with new coronal pneumonia, but with the spread of the disease around the world, gastrointestinal symptoms such as diarrhea, nausea and vomiting have attracted more and more attention. And some patients take diarrhea as the first symptom, which is easy to cause missed diagnosis. This paper expounds the close relationship between COVID-19 and gastrointestinal tract, and reviews the research progress of COVID-19's effect on gastrointestinal tract.
