Background: Respiratory syncytial virus (RSV) is known to cause bronchiolitis and other upper respiratory infections (URIs) in children. However, given the COVID-19 pandemic and the resultant lockdowns, circulation of other respiratory viruses was uncharacteristically low. Restrictions are quickly falling and with increased interaction there has been an uncharacteristic jump in cases.

Purpose: To summarize the pathogenesis of RSV and the mechanisms the virus uses to evade immune responses. Additional discussion of the increased rates of RSV hospitalizations as well as the role of vaccinations in controlling infection.
