Respiratory illness is among the leading causes of death in children under five years of age. Approximately 200,000 deaths in the U.S. and 3.9 million deaths worldwide are attributed to respiratory illnesses. Respiratory illness is also the most frequent reason for physician consultation, with more than 40% of all pediatric outpatient visits related to respiratory illness. According to a recent study, 39% of children attending daycare experienced acute otitis media (ear infection) and 26% reported allergies. Most notably, 10% of children attending daycare were admitted to the hospital due to respiratory illnesses.
