Vertical transmission of human echovirus 11 at the time of Bornholm disease in late pregnancy.

We report a case of human echovirus 11 infection in a neonate at the time of Bornholm disease in late pregnancy of the mother. Mother and baby were found to be infected with the same virus, with a combination of diagnostic virologic techniques, demonstrating likely transmission from mother to baby around the time of delivery.

Coxsackievirus B3 sequences in the blood of a neonate with congenital myocarditis, plus serological evidence of maternal infection.

A fatal case of myocarditis in a neonate is described. The clinical features were evident at birth, and enteroviral RNA was detected in the blood of the baby on the day of birth and again 10 days later by a generic enterovirus nested reverse transcription-polymerase chain reaction (RT-PCR) assay. The enterovirus RNA was subsequently retested by a separate, newly developed nested RT-PCR assay yielding a PCR product within the VP1 coding region suitable for sequencing.
