(RSV) infection from a
common cold. A doctor may suspect RSV infection as the cause of symptoms when
there is evidence of a recent community outbreak. It is generally not necessary
to confirm RSV infection with lab tests. But a
and

A
viral detection test may be done to confirm a
diagnosis of RSV in symptomatic
children and
adults older than 65 who are at an increased risk for
a severe infection or for complications. The test involves lab analysis of
nasal drainage, obtained with a cotton swab or nasal
wash. Testing may also be recommended for people who are hospitalized if the
cause of symptoms has not already been determined and they have a high risk of
developing

detection tests help determine whether precautions are needed to prevent the
