Ratios of MAARI rates attributable to influenza (Knox / Knox-surrounding counties) among school-age children aged 5–17 years

Influenza
season		 ED visits
Rate Ratio		 95% CI Hospitalizations
Rate Ratio		 95% CI
2000–2001 0.83 (0.66, 1.00) 0.78 (*, 1.86)
2001–2002 1.02 (0.74, 1.30) 0.69 (*, 1.57)
2002–2003 0.99 (0.74, 1.24) 0.40 (*, 1.49)
2003–2004 0.88 (0.74, 1.02) 0.83 (*, 1.68)
2004–2005 1.06 (0.79, 1.33) 1.63 (*, 4.08)
2000–2005 0.94 (0.73, 1.15) 0.82 (*, 1.95)

95% CI, confidence intervals. Rate ratios represent Knox rates divided by Knox-surrounding counties rates

*

Ratio was not computed because there was no excess MAARI hospitalizations attributable to influenza in at least one of the populations.
