Onset of allergy and asthma symptoms in extra‐European immigrants to Milan, Italy: possible role of environmental factors

Abstract

Most extra-European immigrants declared that they were healthy at home and that allergy and asthma symptoms had appeared after immigration to Milan; lifestyle and environmental factors in a western industrialized city seem indeed to facilitate allergy/asthma onset in immigrants from developing countries. Allergy/asthma risk seems to be different in different ethnic groups.
