1.  In outpatients with new-onset diarrhea, ascertain information about high-risk contact exposure; obtain a detailed history of symptoms associated with COVID-19, including fever, cough, shortness of breath, chills, muscle pain, headache, sore throat, or new loss of taste or smell; and obtain a thorough history for other Gl symptoms, including nausea, vomiting, and abdominal pain.
2.  In outpatients with new-onset Gl symptoms (eg, nausea, vomiting, abdominal pain, and diarrhea), monitor for symptoms associated with COVID-19, as GI symptoms may precede COVID-related symptoms by a few days. In a high COVID-19 prevalence setting, COVID-19 testing should be considered.
3.  In hospitalized patients with suspected or known COVID-19, obtain a thorough history of GI symptoms (ie, nausea, vomiting, abdominal pain, and diarrhea), including onset, characteristics, duration, and severity.
