Asthma is one of the most common long-term conditions in children, impacting one in 11 of our paediatric population (Asthma+Lung UK, 2025; NHS England, 2025). The multifactorial nature of asthma means that for some patients symptoms are perennial and for some it is very seasonal — it all depends on the trigger factors.

What we do know is a consistent peak for acute asthma in our children and young people — week 38.
