These
county and county equivalent data show the results of tests on blood samples
from sentinel chickens, provided by local health officials. Sentinel chickens
are birds placed in cages that are exposed to mosquitoes in the area. Chickens
that are bitten by infected mosquitoes develop antibodies, but are not otherwise
affected by the virus. Note that the map includes all areas of positive (confirmed
or probable) WNV results, but not necessarily all areas with submitted samples
or no reports.
| Note: These data are provisional and may be revised or adjusted in the future |
