Chinese experts warned about the newly discovered symptoms of COVID-19, including diarrhea, loss of appetite and nausea.

In three hospitals, 204 infected cases have been tested and results have been published in the American Journal of Gastroenterology.

Experts said 48,5% of the cases suffer from digestive system problems as well as respiratory problems.
