Y1 - 2017 N1 - T2 - Maxcy-Rosenau-Last Public Health and Preventive Medicine, 15e AB - Upper respiratory tract infections, mainly common cold and acute pharyngitis, accounted for 10.8% (27.5 million) of all visits to physicians in the United States in 1991.1 In 1–4-year-old children, otitis media is one of the most common reasons for visits to physicians, and accounted for an additional 2.7 million office visits.1 To diagnose and treat upper respiratory tract infections and otitis media costs billions of dollars. Furthermore, the diagnostic criteria for upper respiratory tract infections are often subjective and based on symptoms alone; because of this, treatment varies significantly from physician to physician.2 SN - PB - McGraw-Hill Medical CY - New York, NY Y2 - 2024/04/19 UR - accessbiomedicalscience.mhmedical.com/content.aspx?aid=1141966004 ER -
