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.
