Asthma, which afflicts a staggering number of people worldwide, is triggered by a range of substances - and these allergens are common at home thanks to the presence of dogs, cats, mice, cockroaches, dust mites and fungi.

Significantly, the study showed that homes with children were less likely to have high allergen levels. The authors ascribed this to the greater frequency of cleaning, a simple yet cost-effective method to remove allergens.

The findings of the study have been published in the latest issue of the Journal of Allergy & Clinical Immunology.

The study, which surveyed 2,500 US homes across 75 locations, was the first to characterise how allergen exposures vary in homes.
