The United Kingdom has reported an unusual increase in myocarditis infections and two deaths in babies who had enterovirus infections, the World Health Organization (WHO) said yesterday.
In early April, the UK notified the WHO about an increase in severe myocarditis in infants in Wales. Fifteen cases consistent with neonatal sepsis in babies 28 days old and younger were reported from Wales and Southwest England from June 2022 and March 2023. Polymerase chain reaction (PCR) testing in nine patients confirmed either coxsackie B3 or coxsackie B4. As of April, three patients were hospitalized, four were receiving outpatient care, and two died.
