Multisystem inflammatory syndrome in children

Multisystem inflammatory syndrome in children (MIS-C), or paediatric inflammatory multisystem syndrome (PIMS / PIMS-TS), or systemic inflammatory syndrome in COVID-19 (SISCoV), is a rare systemic illness involving persistent fever and extreme inflammation following exposure to SARS-CoV-2, the virus responsible for COVID-19. Studies suggest that MIS-C occurred in 31.6 out of 100,000 people under 21 who were infected with COVID-19.
