Did you know that “nearly every child will get RSV by the time they are 2 years old?” (Centers for Disease Control and Prevention [CDC], 2024b,).

What is RSV?
Respiratory syncytial virus (RSV) is a common virus that affects the lungs of hosts; about 97% of children are affected by RSV (American Lung Association, 2021). Most people may mistake this for a common cold, or have no symptoms at all. However, infants less than 6 months of age, premature infants, and older adults with poor health are at risk for more severe illness that can lead to bronchiolitis or pneumonia (American Academy of Family Physicians, 2024; CDC, 2024b). These illnesses result in somewhere between 50,000-80,000 hospitalizations of children annually, and twice that for older adults (CDC, 2024c; CDC, 2024b). The symptoms of RSV in infants include a progressive worsening of runny nose, cough, and decreased eating or drinking (CDC, 2024b). Infants less than 6 months old will also present with irritability, decreased activity, and apneic periods (CDC, 2024b). Interestingly, RSV is not associated with fever (CDC, 2024b). RSV infections are seasonal, and typically occur in late fall to winter months in the U.S. However, according to the American Medical Association (AMA), the COVID-19 pandemic disturbed the seasonal nature of RSV, and it has not returned to predictable pre-pandemic patterns (2023). This is relevant because it disrupts the ability to prepare for and prevent typical RSV illnesses, which includes timing of vaccinations.
