In children, the orofecal route is an alternative route of transmission, regardless of presenting COVID 19 symptomatology. Exclusion of SARS-CoV-2 infection by single time point nasopharyngeal swabs should not be used in children.
In March 2020, two infants with SARS-CoV-2 infection were admitted
A 5-month-old boy, with respiratory and gastrointestinal symptoms with diarrhoea. Had positive nasopharyngeal and rectal swabs. The second a 2-months-old, with mild respiratory symptoms, tested positive for SARS-CoV-2 faecally on day 3 from the onset.
The authors also cite evidence from the SARS 1 that fecal excretion could be ongoing even after 30 days from symptom onset.
What did they do?
The study is a short case report of two infants aged 2 and 5 months admitted to hospital in Padova, Italy in March 2020. One had mild GI symptoms, the other mild respiratory symptoms. Both had COVID 19 with positive nasal and rectal swabs. Both were eventually discharged. Because at the time the MoH policy was only to monitor post-discharge using only nasal swabs, the authors undertook a review of the evidence for orofecal transmission.
There is no method chapter and the paper is a descriptive review of the evidence of orofecal transmission and anal shedding up to March. They do not report on whether stool isolates from the 2 children are viable.
|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?
This review of case series needs replication and more evidence must be accumulated.
