Diarrhea and other digestive symptoms are the main complaint in nearly half of coronavirus patients, Chinese researchers report. Most patients with the coronavirus have respiratory symptoms, but these findings from the early stages of the outbreak show that digestive problems are prevalent in many patients with COVID-19.

“Clinicians must bear in mind that digestive symptoms, such as diarrhea, may be a presenting feature of COVID-19, and that the index of suspicion may need to be raised earlier in these cases rather than waiting for respiratory symptoms to emerge,” wrote the investigators from the Wuhan Medical Treatment Expert Group for COVID-19.
