West Nile Virus Found in St. Louis Area Mosquitoes



Mosquitoes found in surveillance traps set up by the Jefferson County Health Department have tested positive for West Nile Virus. The sample was collected on September 23 and was from unincorporated Fenton, MO.

The Jefferson Leader reports that there are 100 sites around Jefferson County with surveillance traps and that this is the second positive sample in the St. Louis area this month — the first was on September 5 in Hillsboro, MO.

In the Jefferson Leader story, emergency response vector technician Scott Darrough said residents should “continue taking measures to avoid mosquito bites and to prevent, or at least minimize, population growth in mosquitoes.”

So if you’re in JeffCo or visiting there soon, you might want to take extra precautions by wearing DEET and avoiding any sources of standing water.
