Bottom Line

An asymptomatic child was positive for a coronavirus by reverse transcription PCR in a stool specimen 17 days after the last virus exposure.

Evidence Summary

After additional stool specimens collected on February 2 (ORF1ab Ct 25.6; nucleoprotein gene Ct 25.8) and February 4 (ORF1ab Ct 25.6; nucleoprotein gene Ct 28.3) were positive, the patient received abidol hydrochloride (100 mg 3×/d), 

Stool specimens collected on February 7 (ORF1ab Ct 26.3; nucleoprotein gene Ct 27.6), February 8 (ORF1ab Ct 31.4; nucleoprotein gene Ct 30.6), and February 9 (ORF1ab Ct 27.0; nucleoprotein gene Ct 27.0) were positive, but stool specimens collected on February 12 and 14 were negative.

What did they do?

On January 30, 2020, a 10-year-old boy who had no fever or cough but had close contact with 2 confirmed case-patients with laboratory-confirmed COVID-19.

Study reliability

Clearly defined setting Demographic characteristics described Follow-up length was sufficient Transmission outcomes assessed Main biases are taken into consideration
Partly Partly Yes Yes No
