Respiratory syncytial virus, or RSV, is a common respiratory virus that usually causes mild, cold-like symptoms. Most people recover in a week or two, but RSV can be serious, especially for infants and older adults. RSV is the most common cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia (infection of the lungs) in children younger than one year of age in the United States.
Most RSV infections go away on their own in a week or two.
There is no specific treatment for RSV infection, though researchers are working to develop vaccines and antivirals (medicines that fight viruses).
Is this a reportable illness?
This is not a reportable illness to CDPH but consult with your school nurse to confirm this diagnosis with parents or the medical provider.
Please note there is no need to report RSV clusters in daycare centers.
What do schools need to do next?
No exclusion unless febrile or other symptoms meeting exclusion criteria are present.
