Nosocomial staphylococcal cervical lymphadenitis in infants: report of an outbreak

Abstract

Staphylococcus aureus infections developed in 16 of 721 infants born at a general hospital during a six-month period (October 1972 to March 1973). Twelve of the 16 affected infants had cervical adenitis, which usually became manifest two to four months after they were discharged from the hospital. Although most infants with adenitis underwent incision and drainage procedures, physicians noted few constitutional symptoms. Staphylococcal phage types from infants with adenitis were identical to phage types commonly recovered from colonized newborns and nursery personnel at the hospital. Despite the long period between hospital discharge and onset of clinical symptoms, cases of cervical adenitis were probably nosocomial in origin.
