When they presented to a hospital, 99 of the 204 people — or 48.5% — were experiencing digestive symptoms.
The main digestive symptoms among the study cohort were a lack of appetite, in 83 individuals, and diarrhea, in 29.
Other symptoms included vomiting, in eight individuals, and abdominal
pain, in four.
The study authors also note that seven of the patients with COVID-19 had no respiratory symptoms but did experience digestive symptoms.
Moreover, the digestive symptoms among the larger group grew more severe as the severity of COVID-19 increased, the researchers report.
