Abstract
Background: An outbreak of respiratory tract infection due to Respiratory Syncytial Virus (RSV) type B in a postpartum center was reported on February 1, 2017. Investigation was conducted to identify the magnitude, possible source of infection and risk factors for this outbreak on February 2, 2017. Methods: A retrospective cohort study was conducted. A case was defined as a neonate having respiratory symptoms with or without fever and stayed at the postpartum center between January 1, 2017 and February 3, 2017. Daily records of neonates were reviewed, and all parents who stayed at the postpartum center were interviewed. Virological testing of real-time polymerase chain reaction was conducted for the neonates having respiratory illness, the parents and all staff members in the facility. Results: This outbreak occurred between January 17, 2017 and February 7, 2017 in a postpartum center. Thirty-five (58.3%) neonates among 59 neonates were identified as cases and 12 neonates were confirmed to be RSV-B positive. The longer length of stay in the postpartum center is the only risk factor (Relative Risk = 8.10, 95% Confidence Interval:1.84–35.62, p < 0.01) in this outbreak. Two nursing staffs and eight parents were confirmed as RSV-B positive. Conclusions: Longer periods of stay in the postpartum center had an increased chance of becoming infected with RSV during this outbreak. Isolation of cases and temporary closure with environmental cleaning were recommended to the postpartum center.
