Influenza-associated myositis: a single-centre, 5-year retrospective study

Conclusion: Childhood viral myositis shows strong association with the influenza season. IAM is clinically stereotyped, age restricted, and benign in most and strongly associated with influenza B.What is Known:• Childhood viral myositis has been reported in association with influenza for decades, more frequently with influenza B and in school-aged children.What is New:• Here, we show over a 5-year period that viral myositis is strongly seasonal with up to 80% of cases attributable to influenza.• Influenza-associated myositis (IAM) typically occurs in boys, aged 5–9 years, with influenza B and is most often benign. Early clinical recognition may avoid unnecessary treatment and testing.
