Bronchioles, the two smallest airways present in the lungs get infected with the virus, causing swelling and then inflammation in them. These airways get blocked due to formation of mucus, making it difficult for air to flow in freely into and out of the lungs. RSV infection outbreak occurs generally in the winter season. Common cold and flu are other viruses that could cause bronchiolitis. When a sick person talks, sneezes or coughs, the virus spreads easily through droplets in the air.  The virus also spreads by touching objects such as toys, towels or utensils infected with the virus and then touching the mouth, nose or eyes.
