Positive Stool Test Results Suggest that the Discharge Standard for COVID-19 Needs Improvement.

We report on a hospitalized patient with 2019 novel coronavirus disease whose fecal samples tested negative 22 days after respiratory samples tested negative, highlighting that the duration of viral shedding is longer than that previously expected. Current clinical examinations for treatment and discharge standards are limited to respiratory samples. However, we believe that nucleic acid testing of both respiratory and fecal samples is necessary for discharging patients. Further studies are needed to confirm the potential of fecal-oral transmission or fecal-respiratory transmission via aerosols.
