In brief: Variable, 1-2 weeks

In adults and older children, RSV is usually mild viral URI with nasal congestion and cough that lasts 1-2 weeks.
In infants and young children with chronic medical problems, RSV can cause severe bronchiolitis with wheezing and cough that can require hospitalization and in extreme cases can cause death.

In brief: A week or more

Symptoms of RSV vary with the kid with age, state of health & immunity.
Most will actively shed virus for 3-8 days and the sickest from 4-6 wks. The few hospitalized infants seldom stay more than 5 days.
