There have been rumours that COVID-19 is milder in children and adolescents or even that it doesn’t occur in children at all. That narrative is changing. Not only do infants seem to experience more severe illness than older children, but even children with milder symptoms need to be hospitalised. On top of this, a severe inflammatory syndrome that affects multiple organs is now thought to be caused by COVID-19 and affects children at a higher rate than adults. This theory that children are safe from COVID -19 becomes more and more unlikely every day.
A study conducted in Paris explicitly draws a connection between shock syndrome and Covid-19.
Multisystem inflammatory syndrome seen in children and adolescents in Paris may be linked to COVID-19.
To describe the features of a multisystem inflammatory syndrome that may be related to COVID-19 infections in children and adolescents.
Observational study in which 21 people aged 18 and under admitted to hospital between 27th April and 11th May 2020. The study looked at clinical and biological data, imaging and echocardiographic findings, treatment, and outcomes.
All people had gastrointestinal symptoms and high amounts of inflammation. 90% were found to be positive for COVID-19. 57% presented with a shock syndrome. 76% had myocarditis. 81% needed support from an intensive care unit.
There is likely a causal link between the COVID-19 outbreak in Paris, France and the rising cases of inflammatory syndrome seen in children and adolescents.
Potential recruitment bias
Small sample size
Household members not tested for ongoing infection
Small chance of false positive COVID-19 tests
Echocardiographic tests - using sound waves to create moving pictures of your heart
Gastrointestinal symptoms - stomach problems such as heartburn, indigestion/dyspepsia, bloating and constipation
Myocarditis - inflammation of the heart
Multisystem - involving more than one organ
