Three children with mild symptoms who were SARS‐CoV‐2 throat swab specimen negative on discharge from hospital were stool positive 10 days post-discharge
Case series of three male children aged 6, 8 and 9 whose parents had COVID-19. The children were admitted to hospital with mild symptoms and given a variety of treatments, after which they tested negative throat swab nucleic acid at 7, 11 and 14 7 days, and were discharged from hospital. On follow up they again tested negative at 9, 13 and 16, 13 days respectively.
Post-discharge stool SARS‐CoV‐2 nucleic acid tests were positive at 10 days. The three patients were readmitted with no clinical symptoms nor pathological changes in lung Imaging. Post readmission the stools were negative at 4, 5, and 10 days.
Stool positivity can, therefore, persist up to 20 days form symptom onset, and recovered patients might be possible carriers of the virus.
What did they do?
The study describes the clinical pathway followed by the three boy cases. Histories, imaging and lab results are reported.
The case series is small.
|Clearly defined setting
||Demographic characteristics described
||Follow-up length was sufficient
||Transmission outcomes assessed
||Main biases are taken into consideration
What else should I consider?
The results of this small case series need replicating. No mention of the viability of Co-V recovered from stools is made.
