Prolonged virus shedding is observed in the respiratory tract and feces of children at the convalescent stage.
None of the ten patients had diarrhoea or dyspnea during the course of illness. 2019-nCoV RNA was detected in nasopharyngeal and throat swabs from all patients within 4-48 hours after symptom onset. Six patients had fecal samples tested within 3-13 days after illness onset and 5 (83%) showed positivity
What did they do?
Between 19 January and 3 February 2020, a total of ten children with confirmed 2019-nCoV infection were admitted to the Children’s Hospital in Shanghai, Hainan. A duplex one-step real-time RT-PCR was performed to confirm infection at the local CDC reference laboratory.
A cycle threshold value less than 35 was defined as a positive test.
