Brief Summary

The purpose of this study is find out if MT (mid-turbinate) swabs can be used to correctly measure viral loads in the same way that NP (Nasopharynx) swabs do. MT swabs are more comfortable for the patient, but there is little data on their use in viral load measurement. This study will compare viral load measurements from patients who have both types of swab (NP and MT) performed. Medical data will be collected from this RSV hospitalization to help us understand how the viral load information relates to how sick the child is.



  1. Compare the RSV viral load from flocked swabs collected from the nasopharynx  (NP) vs. the middle turbinate (MT) of infants <24 months admitted to the hospital with symptomatic RSV infection.
  2. Evaluate the relationship between RSV viral load and RSV symptoms and severity
