Rhinoviruses are by far the most common cause of the “common cold” (responsible for ~50–80% of URIs) and circulate year-round. Although typically causing mild illness, rhinovirus can infect lower airways and is a leading trigger of asthma and chronic airway. Testing for rhinovirus helps interpret respiratory symptoms and can identify outbreaks (Tobin et al. 2025, Esneau et al 2022).
