Abstract

We characterized a recombinant mosaic coxsackievirus A9 strain responsible for severe inflammatory cardiomyopathy in a previously healthy child in northeastern France in 2024 by using whole-genome sequencing. This case highlights that enterovirus species other than coxsackievirus strain B3 can cause cardiomyopathy in otherwise healthy pediatric patients.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
