The majority of children below the age of 2 years who only wheeze with URTI and have no interval symptoms will be free of recurrent respiratory symptoms by thetime they go to school. A minority will go on to wheeze in response to other triggers, will experience symptoms between acute episodes, and are less likely to 'growout of it'. As a general rule, the earlier the onset of wheeze the better the prognosis, although the co-existence of atopic conditions, such as eczema, increases therisk of the child going on to develop asthma.
