Outbreak of human adenovirus type 3 infection in a pediatric long-term care facility--Illinois, 2005.

Background: Human adenovirus type 3 (HAdV-3) causes severe respiratory illness in children, but outbreaks in long-term care facilities have not been frequently reported. We describe an outbreak of HAdV-3 infection in a long-term care facility for children with severe neurologic impairment, where only 3 of 63 residents were ambulatory.

Methods: A clinical case of HAdV-3 was defined as fever (temperature, > or = 38.

Transmission of methicillin-resistant Staphylococcus aureus to preterm infants through breast milk.

Objective: To determine a potential source of MRSA colonization and infection among preterm infants in a neonatal intensive care unit (NICU) using molecular analysis of breast milk samples.

Design: Case report, outbreak investigation.

Results: Preterm triplets were delivered at 26 weeks' gestation via cesarean section when routine active surveillance for MRSA was performed for all infants in a NICU.
