An echovirus type 22 outbreak involving 19 neonatal intensive care unit (NICU) patients
during the months of October and November 1992 is reported. Twelve infants presented
with diarrhea, 7 of whom had bloody stools and x-ray findings compatible with early
stages of necrotizing enterocolitis, while one infant demonstrated characteristic
pneumatosis intestinalis. Outbreaks of echovirus type 22 infection in premature infants
have rarely been reported. The possibility of Echovirus 22 infection should be considered
in neonatal gastrointestinal disease associated with features of necrotizing enterocolitis.
