RESUMO
OBJECTIVE: The respiratory syncytial virus (RSV) is the most significant viral pathogen causing bronchiolitis and pneumonia in infants, today. In tropical climates the RSV infection may occur throughout the year. The purpose of this study was to asses RSV infections during the 2009â2010 RSV season in children under 2 years of age and to evaluate the trend of positive RSV tests in the period of 2007 to 2009. METHODS: A retrospective review of data collected from 6 hospitals in Puerto Rico was performed. Patients with confirmed RSV bronchiolitis were included in the study. RESULTS: A total of 4,678 patients were included. The mean age of the patients was 7 months. Data showed that RSV infection occurred throughout the studied months. CONCLUSION: Data confirms a year-round presence of RSV in Puerto Rico. The RSV surveillance system needs to be reinforced to establish and understand the epidemiology of RSV and to review the current immunoprophylaxis guidelines.

BACKGROUND: Respiratory syncytial virus (RSV) is an important cause of respiratory tract disease in infants and young children. Immunoprophylaxis is available for high-risk infants. This study reviews infants with bronchiolitis at three primary care hospitals to describe the epidemiology of RSV infection in Puerto Rico. METHODS: We analyzed data from 2 hospitals by obtaining the number of infants diagnosed with bronchiolitis and estimating the percentage of cases due to RSV. A third hospital included patients with confirmed RSV infection. RESULTS: There were 4,557 patients in the study. RSV infection occurred throughout the year. Data shows a progressive decrease in RSV-positive infections. CONCLUSIONS: Data confirms year-round incidence of RSV in Puerto Rico. A standardized surveillance system in Puerto Rico is imperative to determine RSV epidemiology. The decrease in positive RSV infections may be due to the introduction of immunoprophylaxis to high-risk patients.
