  • 1 Number in parentheses indicates number of deaths.
  • 2 Includes three WN Fever cases.
  • 3 Includes four WN Fever cases.
  • 4 Includes one WN Fever case.
  • 5 Includes two WN Fever cases.

  • Not all animals testing positive are necessarily ill or symptomatic of WNV infection. Some specimens are tested only for surveillance purposes.
  • The total number of WNV-positive mammals or birds depends on the amount of surveillance and testing in each county, and is not necessarily associated with degree of WNV risk; however, risk can be elevated in counties with elevated dead crow densities.
