COST INCURRED BY DISEASE

Table A19–2 summarizes the health care costs incurred by PIV infections. For the purposes of the calculations in this report, it was assumed that all children 2 years of age and under with PIV disease receive medical treatment. It was assumed that only 50% of people between the ages of 2 and 64 receive treatment for PIV disease. It was also assumed that only 50% of people 65 years of age and older receive treatment for mild (requiring only outpatient treatment if treated) pharyngitis and bronchiolitis. A small number of people age 65 years of age and older are hospitalized for bronchiolitis and pneumonia.

Pharyngitis, otitis media, croup, and outpatient treatment of bronchiolitis/pneumonia were assumed to be associated with physician visits, diagnostics and medications. The more serious disease incurred more visits to the physician. Hospitalization costs are included for the small number of people with PIV disease who require it.
