The deeper explanation
The answer in detail
Sensitisation can develop after repeated exposure, infection or changes in the skin and airways. Adult-onset symptoms may also reveal an allergy that was previously mild or unnoticed.
Why it matters

The public system around some allergies begin in adulthood

Starting conditions
History, resources and institutional capacity set the starting position before the visible outcome appears.
Limits and trade-offs
Rules, capacity and competing priorities limit which responses are practical, even when several options look possible.
Choices and distribution
The outcome depends on who can change those conditions and how its consequences are shared.
