This week, Richardson had mosquitoes test positive for the West Nile virus for the fifth time this year. The City of Richardson conducts ground spraying in neighborhood zones with positive traps.
Though no human cases of the disease have been reported in Richardson, Richardson residents shouldn't let down their guard when it comes to protection from mosquito bites. It's important to practice the Four D's of Protection:
The City of Richardson tests mosquitoes weekly, April-October, and works in conjunction with other cities and health agencies in the Metroplex to mitigate the spread of vector-borne illnesses.
