SR Print(0) ID 1141411088 T1 COMMON VIRAL RESPIRATORY INFECTIONS T2 Harrison's Infectious Diseases, 3e YR 2017 FD 2017 PB McGraw-Hill Education PP New York, NY SN 9781259835971 LK accessbiomedicalscience.mhmedical.com/content.aspx?aid=1141411088 RD 2024/04/16 AB Acute viral respiratory illnesses are among the most common of human diseases, accounting for one-half or more of all acute illnesses. The incidence of acute respiratory disease in the United States is 3–5.6 cases per person per year. The rates are highest among children <1 year old (6.1–8.3 cases per year) and remain high until age 6, when a progressive decrease begins. Adults have 3–4 cases per person per year. Morbidity from acute respiratory illnesses accounts for 30–50% of time lost from work by adults and for 60–80% of time lost from school by children. The use of antibacterial agents to treat viral respiratory infections represents a major source of abuse of that category of drugs.
