Coxsackie A10 virus infection among infectious hepatitis contacts.

During an outbreak of infectious hepatitis at a housing development, Coxsackie A10 virus was recovered from the stools of 45 different contacts and from the blood of four others. Caution should be exercised in attributing an etiological role to any given isolate of a Group A Coxsackie virus in view of the widespread distribution of these organisms. Nevertheless, the recovery of Coxsackie A10 viruses from the blood and stools of contacts with hepatitis cases appears to warrant record.
