Rapid risk assessment: Paediatric inflammatory multisystem syndrome and SARS -CoV-2 infection in children

Several countries affected by the coronavirus disease (COVID-19) pandemic recently reported cases of children that were hospitalised in intensive care due to a rare paediatric inflammatory multisystem syndrome (PIMS). The presenting signs and symptoms are a mix of the ones for Kawasaki disease (KD) and toxic shock syndrome (TSS) and are characterised, among others, by fever, abdominal pain and cardiac involvement. A possible temporal association with SARS-COV-2 infection has been hypothesised because some of the children that were tested for SARS-CoV-2 infection were either positive by polymerase chain reaction (PCR) or serology.
