Trends of Respiratory Syncytial Virus Infections in Children under 2 Years of Age in Puerto Rico.

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 2009‒2010 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.

Respiratory syncytial virus-related bronchiolitis in Puerto Rico.

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.
