Respiratory Syncytial Virus (RSV): Information for Providers
Testing
With multiple co-circulating respiratory viruses during the fall and winter, diagnostic testing for RSV, influenza, COVID-19, and other respiratory viruses can help guide treatment and clinical management. Consider diagnostic testing for patients with suspected respiratory virus infections, particularly hospitalized patients, those with severe or progressive illness, and those with factors placing persons at high risk for severe outcomes from RSV, influenza, and COVID-19.
Several laboratory tests are available for confirming RSV infection, including:
- Real-time reverse transcriptase-polymerase chain reaction (rRT-PCR), which is more sensitive than culture and antigen testing
- Antigen testing, which is highly sensitive in infants and young children but not as sensitive in older children and adults
Less commonly used tests include:
- Viral culture
- Serology, which is usually only used for research and surveillance studies
Providers should consult experienced laboratorians for more information on testing and interpretation of results.
Treatment
Most cases of RSV will resolve without treatment. For supportive care, inform patients and parents to:
- Manage fever and pain with over-the-counter fever reducers and pain relievers, such as acetaminophen or ibuprofen. (Never give aspirin to children.)
- Drink plenty of fluids. It is important for people with RSV infection to drink enough fluids to prevent dehydration.
