Asthma and chronic rhinosinusitis (CRS)-;sinus inflammation that lasts for at least three months-;are serious and costly diseases, and both are on the rise. According to the American Academy of Allergy, Asthma and Immunology, CRS affects up to 16 percent of the U.S. adult population and eats up a staggering 5 percent of the country’s health care budget each year. Asthma, which involves inflammation of the lower airway, affects about 8 percent of the population and costs about $56 billion annually in health care and lost time, according to the Centers for Disease Control and Prevention.

The National Institutes of Health (NIH) recently awarded two Northern Arizona University researchers $468,472 to study how microbiota in the upper and lower airways drive inflammation in patients with these respiratory tract diseases.
