Prevalence rates of asthma in developing countries and their comparison with those in Europe and North America

J B Cookson. Chest. 1987 Jun.

Abstract

Prevalence rates for asthma in various parts of the world are different and this cannot be entirely explained by differences in methodology. Low prevalence rates are found in third world countries, particularly marked for children. The reasons for these differences are obscure but are largely environmental. Some suggestions are made herein about their nature.
