Bronchiolitis is primarily caused by viral infections of the small airways in the lungs. According to available information, several respiratory viruses can lead to bronchiolitis.
Common Viral Causes of Bronchiolitis
The primary culprits behind bronchiolitis include, but are not limited to:
- Respiratory Syncytial Virus (RSV): A very common cause, and infants infected with RSV have a higher likelihood of developing bronchiolitis with symptoms like wheezing and difficulty breathing.
- Influenza Viruses: These viruses, which cause the flu, can sometimes lead to bronchiolitis.
- Parainfluenza Viruses: Another group of viruses known to cause respiratory illnesses, including bronchiolitis.
- Human Metapneumovirus: A virus similar to RSV that can also cause bronchiolitis.
Other viruses can also cause bronchiolitis, though they are not specifically named in the provided information.
Bronchiolitis and RSV
As noted in the provided reference from October 9, 2023, infants infected with RSV are particularly susceptible to developing bronchiolitis accompanied by wheezing and breathing difficulties. This highlights RSV as a major concern regarding this illness.
