I Have Something to Say

What role do children play in transmission?
The fact that children are less likely to show symptoms when infected with SARS-CoV-2 has raised concerns that they may be responsible for covert virus transmission, though there is little direct evidence to suggest that asymptomatic children are playing a major role in spreading the disease. One study which analysed the source of 31 household clusters of COVID-19 in China, Singapore, South Korea, Japan, and Iran found that children were the source of infection in just three of these cases.[13] The China/WHO joint commission, a panel of international experts which investigated the initial COVID-19 outbreak in China, found, by contact tracing, no cases where transmission occurred from a child to an adult.[14] Possibly, the early closure of schools, combined with children’s apparent reduced susceptibility to infection, may have limited transmission from children. However, the absence of coughing in milder or asymptomatic cases may reduce transmission of the virus. Further studies are needed to test this idea.

Although the role children play in transmitting the virus is unclear, evidence consistently demonstrates that children are less likely than adults to acquire infection, and less likely to bring infections into households.[10]

Transmission
Precise details regarding paediatric transmission are still being ascertained, however important trends are emerging. Low case numbers in children suggest a more limited role than was initially feared. Contact tracing data from Asia, the USA, Europe and Israel have all demonstrated a significantly lower attack rate in children than adults, including testing of asymptomatic household contacts on both PCR and serology. Coupled with low case numbers would suggest that children are less likely to acquire the disease. The role of children in passing the disease to others is unknown, in particular given unknown numbers of asymptomatic cases. Notably, the China/WHO joint commission could not recall episodes during contact tracing where transmission occurred from a child to an adult. Studies of multiple family clusters have revealed children were unlikely to be the index case, in Guangzhou, China, Israel, the USA, Switzerland and internationally. Limited data on positive cases in schools have not demonstrated significant transmission, except within adolescent populations. Studies of younger children in schools have found low rates of transmission, but with very low case numbers.

Several studies have now shown that SARS-CoV-2 can be detected by PCR in the stool of affected children for several weeks after symptoms have resolved. Studies have confirmed there can also be live virus found in the stool of infected individuals. How much virus is present, and the extent to which faecal-oral transmission may be possible is yet to be confirmed.
