Link: Children and antibiotics
Children during their first year of life are prescribed antibiotics for many reasons, primarily ear infections and respiratory infections. Many of these illnesses turn out to be viral in nature, and so the antibiotics are unnecessary. Now there may be another reason to avoid antibiotics.
Researchers at the University of British Columbia examined studies of data from more than 12,000 children and 1,800 asthma cases and found that children who took at least once course of antibiotics when they were under one year old were more than twice as likely to develop asthma as children who never took antibiotics.
