Contact with dogs during the first year of life is associated with decreased risk of respiratory illness

Context Several groups have studied the associations between animal contacts early in life and asthma and allergic diseases in childhood. Reports on the association between pet exposure and respiratory infection are sparse. Results have been inconsistent, due to retrospective evaluation, study of children of different age groups and having no separate analysis of different pets. Bergroth and colleagues explored the association between dog and cat contacts during infancy and respiratory illnesses during the first year of life by using weekly diaries filled in by the parents.
