In most cases of asthma in children, multiple triggers or precipitants are recognized, and the patterns of reactivity may change with age. Treatment can also change the pattern. Wheeze is common with respiratory syncytial virus (RSV) bronchiolitis and recurrent wheeze may persist up to 3-5 years. However, RSV is unlikely the sole explanation for the development of atopic asthma later in life. On the other hand, infection with human rhinovirus that requires hospitalization has been associated with future development of asthma (age 6 y).
