A Large Outbreak of Influenza B-associated Benign Acute Childhood Myositis in Germany, 2007/2008

Abstract

Influenza B caused a large BACM outbreak in Germany. Onset of BACM symptoms followed shortly after the onset of influenza symptoms. The course of this disease was almost exclusively mild and self-limiting. Diagnosis of this rare but distinct clinical entity by the alert physician can spare the patient potentially unneeded invasive testing and hospital admission.
