About RSV (Respiratory syncytial Virus)
- Respiratory syncytial (RSV) is a common respiratory virus that usually causes mild, cold-like symptoms.
- However, in some cases, RSV can cause more severe infections such as bronchiolitis (an inflammation of the small airways in the lungs) and pneumonia (an infection of the lungs).
- Some groups, including infants and older adults, are more likely to develop severe RSV and need hospitalization.
