Outbreak of severe myocarditis in England: Havoc by a harmless virus.

The recent elevation in numbers for reported severe myocarditis in neonates within Wales and South West England, linked to enterovirus infection, poses a significant public health concern. Myocarditis caused by enteroviruses, particularly Group B coxsackieviruses, is associated with significant mortality rates. Diagnosis is supported by non-invasive techniques and cardiac enzyme blood tests. Treatment modalities primarily involve a palliative approach.
