RESUMO
OBJECTIVE: To determine whether the restriction of young sibling (<13 years) visitation in the neonatal intensive care unit (NICU) during the respiratory syncytial virus (RSV) season was associated with a reduction in the rate of RSV infection among NICU patients. STUDY DESIGN: A retrospective chart review of all RSV positive infants from the 2001-2010 RSV seasons. The 2001-2006 RSV seasons (group 1) contained 639 admissions and the 2007-2010 (group 2, with sibling restriction) contained 461 admissions. Groups were compared by using the Fisher's Exact Test. RESULTS: There was a reduction of RSV positive infants from 6.7% in Group 1 to 1.7% in Group 2 (P<0.0001). There was a reduction of symptomatic infants from the number of infants with symptomatic RSV infection from 23/639 infants with young sibling visitation to 2/461 (P<0.001). CONCLUSION: Exclusion of young sibling visitors <13 years of age during RSV season was associated with a significant reduction in the number of RSV positive infants in the NICU.
