The West Nile Task Force issued a media release last night due to a positive result on a “sentinel chicken” blood test.  These “red-leghorn” chickens are placed in six (6) locations throughout this county.  The positive test came from Roberts Island area, in the southwest area of Stockton.

What does this mean?  All 14 other positive tests came from dead birds turned in by citizens.  Thos birds could have flown in from other counties.  However, a sentinel chicken isn’t transient and means WNV is here!  Still no positive human or equine cases . . . Yet.

We are now entering the 2-month peak period.
