The purpose of this study is to collect nasal and nasopharyngeal (nose and throat) swab samples from people suspected of having the flu or RSV to help make new tests for detecting Influenza A&B and RSV, and/or make current tests better.

The study doctor or study staff member will collect either two (2) nasopharyngeal (nose and throat) swabs or one (1) nasal and (1) nasopharyngeal (nose and throat) swab from you. Standard collection techniques will be used. If the collection of a nasal or nasopharyngeal swab is part of your standard of care that swab will be collected first. The entire process will take about 10-20 minutes of your time.
