Summary:
Scientists are gaining a better understanding of the complex relationship between cat exposure and the risk of developing asthma. For many years, scientists thought that cat exposure increased a child's asthma risk. Recent studies, however, have suggested that exposure to high levels of cat allergen during infancy can actually protect children against developing asthma. This week, a new study supported by the National Institutes of Health (NIH) adds another twist to the developing story.

Scientists are gaining a better understanding of the complex relationship between cat exposure and the risk of developing asthma. For many years, scientists thought that cat exposure increased a child's asthma risk. Recent studies, however, have suggested that exposure to high levels of cat allergen during infancy can actually protect children against developing asthma. This week, a new study supported by the National Institutes of Health (NIH) adds another twist to the developing story. The new study confirmed the protective effect of cat exposure for at-risk children in all but one situation: when the child's mother has asthma. If the mother has asthma, then a cat in the home actually triples the risk that a child will develop persistent wheezing — an initial indication of asthma — by age five.
