Bronchial asthma in the southern Maldives.

A whole population survey was performed in Addu Atoll, southern Maldives to establish the prevalence of bronchial asthma. Assessments of atopic eczema, allergic rhinitis, conjunctivitis and intestinal infection were made, and serum specific IgE titres to a number of allergens were measured. Asthma is a common condition in the southern Maldives, and there is no evidence that the IgE produced by intestinal helminths prevents the condition.
