RESUMO
Hay fever is an allergy to pollen or spores presenting as an allergic inflammatory response in all mucous membranes of the upper airway. The UK has one of the highest rates (it's estimated one in four of us have hay fever) and symptoms are often trivialised, even though the socio-economic and health costs are huge. If left treated, for example, a hay fever sufferer risks developing asthma. Also paediatric allergists now consider the combination of eczema and hay fever to be a significant marker, indicating an atopic child's propensity to develop more serious allergic disease. Unfortunately childhood hay fever is often poorly treated, but a combination of sensible allergen avoidance measures and appropriate medication or treatments is usually sufficient to control symptoms.
