Suggestions on epidemiological investigation of 2019-nCoV infection in all non-febrile outpatient and inpatient departments of the medical institutions

At present, the prevention and control of the coronavirus disease has entered a critical stage. Most patients started with respiratory symptoms such as fever and/or cough, but some of them had diarrhea or even no symptoms. According to the current finding, the Virus can infect not only the respiratory system, but also the digestive system. For this reason, we suggest that we should expand the screening scope of patients with 2019 novel coronavirus infection, and carry out epidemiological investigation on patients with diarrhea and other digestive system symptoms in non-febrile outpatient and inpatient departments. It will help to find patients who may have missed diagnosis, and also can provide scientific basis for more active and efficient control of the transmission of 2019 novel coronavirus, especially in hospital.
