What causes bronchiolitis? | Dr. Parthiv Shah | Best Pulmonologist in Mumbai

The respiratory syncytial virus (RSV), rhinovirus, and influenza (flu) virus are the viruses that cause the majority of instances of bronchiolitis. These viruses are very infectious, and they are passed from person to person by touching secretions from the mouth or nose, or by respiratory droplets in the air. When someone sneezes or coughs, the droplets enter the air.
