3. Fig. 2
Estimated annual norovirus cases in older adults (≥65 years old) in the United States in 2015, by outcome. To generate case counts, incidence rates by outcome were obtained or calculated from existing literature (aHall and colleagues, ; bLopman and colleagues,4 2011; cGastañaduy and colleagues,5 2013; and dGrytdal and colleagues, ) and multiplied by the US population estimate for older adults in 2015 (47.8 million). For deaths and emergency department visits, 95% CIs are shown in parentheses; for outpatient visits, the average from 2 studies is shown; for hospitalizations, high and low seasonal estimates from 1996 to 2007 are shown; for total illnesses, 95% credible intervals are shown. All numbers are rounded to 2 significant digits. Data collected at the community level are used as proxy for determining total illnesses.
