    Abstract:
    AIM: Serratia marcescens is a rare, but important, pathogen in hospital-acquired infections, especially in neonatal units. Outbreaks may cause significant mortality among neonates. This study describes how an outbreak of S. marcescens was handled in a neonatal intensive care unit in Finland in June 2015. METHODS: Tampere University Hospital is the only hospital that offers intensive care for preterm neonates in the Pirkanmaa health district area in Finland. Between June 9, 2015 and June 29, 2015, seven neonates were screened positive for S. marcescens in the hospital. We examined the management and outcomes, including environmental sampling. RESULTS: Two of the seven neonates developed a bloodstream infection, and one with S. marcescens sepsis died after six days of antibiotic treatment. The outbreak was rapidly managed with active hospital hygiene interventions, including strict hand hygiene, cleaning, patient screening, contact precautions and education. Environmental sampling was limited to one water tap and a ventilator, and the results were negative. The outbreak was contained within three weeks, and no further cases appeared. The screening of healthcare workers was not necessary. CONCLUSION: A S. marcescens outbreak caused significant morbidity in neonates and one death. Rapid hospital hygiene interventions and patient screening effectively contained the outbreak.
