ICD-Code J21.0: Acute bronchiolitis due to respiratory syncytial virus
The smallest airways in your lungs are inflamed.
The air is breathed in through the mouth or nose. From there the air goes into the trachea via the larynx. At the end of the windpipe are two bronchial tubes (or bronchi) branching away from it. The bronchial tubes run into the lungs. What is more, the bronchial tubes divide into even smaller branches. The larynx, the trachea, the bronchia and the lungs are part of the lower airways. The smallest bronchial tubes are called bronchioles.
This inflammation was triggered by certain viruses. These viruses are called respiratory syncytial viruses.
Inflammation can cause the bronchioles to narrow. This can lead to shortness of breath. Coughing and fever may also occur.
