Bronchiolitis (and RSV)

We have started to see cases of bronchiolitis, a viral illness (sometimes caused by RSV -- "respiratory syncytial virus") that occurs most often in children under age 2. This virus typically occurs in epidemics during the winter and the early spring. "Bronchioles" are the smallest airways in our lungs, and "itis" means these airways are inflamed, or irritated, by the virus. When these airways get inflamed in young children, they may start to "wheeze," and air and the oxygen in it have difficulty getting through these narrowed, swollen airways.


With a case of bronchiolitis, your infant's symptoms may begin with a runny nose, a fever, and a harsh, tight cough. If it progresses to wheezing, your child may start to breathe rapidly and "pull" with his/her abdomen and rib muscles with each breath. Please call us for an appointment if your child's breathing becomes labored or difficult.


An immunization against RSV is approved to protect babies under 8 months of age during RSV season.This form of antibody against RSV is administered once by an injection. In large, controlled studies, this product has been shown to decrease hospitalization from RSV infections in infants.
