Bronchiolitis (and RSV)
We are currently seeing 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 often will start to "wheeze," meaning 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.
Beyfortus is a monoclonal antibody with activity against RSV. Monoclonal antibodies are laboratory-made proteins that mimic the immune system’s ability to fight off harmful pathogens such as viruses. One dose of Beyfortus, administered as a single intramuscular injection prior to or during RSV season, may provide protection during the RSV season.
Beyfortus (Nirsevimab) is recommended for: All infants younger than 8 months of age born during RSV season or entering their first RSV season.
