Figure 5. Projected proportion of each state's population infected with West Nile virus versus the proportion of the state's population reporting neuroinvasive disease cases to the Centers for Disease Control and Prevention's ArboNET program. Data are excluded for 13 states: 6 states with neither minipool–nucleic acid amplification testing (MP-NAP) yield nor neuroinvasive cases, 6 states with 2 to 12 neuroinvasive cases but no MP-NAT yield, and 1 state with 1 MP-NAT–positive donor but no reported neuroinvasive cases.
