To date, we have had over 200 cases of West Nile Virus reported in Dallas County. Of the 200, Ten People have died. For Texas (Dallas specifically), this is the worse case of WNV we have seen for quite some time.
Since this is the case, Mayor Mike Rawlings declared a state of emergency and agreed to the first Aerial Spraying of insecticide since 1966. Im not sure how serious it was in 1966, or if it was due to WNV, but that was the last Aerial Spraying reported.
Its said that Aerial Spraying could begin as early as this evening. If you plan on being outdoors, try not to be out there sunset or sunrise. That time seems to be when Mosquitos are most active. And if you do need to be outside, be sure to use bug spray.
