Bronchiolitis (and RSV)

Bbronchiolitis is a viral illness most commonly caused by the RSV virus often in children under age 2. This virus typically occurs in epidemics during the winter and the early spring in the northern states; however, here in Florida it is a year-round virus.

"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. If your child is in extreme respiratory distress please call 9-1-1 or go to the nearest emergency department. 

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, 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. Also recommended for children up to 24-months of age who are at risk for sever RSV disease (children with congenital heart disease, extremely premature infants, and any other illness or disease state that may cause an immune deficiency state.
