Asthma link to frequency of early life infections

Danish researchers found among 313 children followed from birth that 15% developed asthma by the age of seven.

No association was found between the type of virus or bacteria acquired and later asthma, but there was an association between the number of infections experienced and asthma.

The findings suggest individual susceptibility provoking an exaggerated response to infection may be behind the development of asthma, the authors said.
