Two More Mosquitoes Test Positive For West Nile Virus In Phoenixville

Two more mosquitoes have tested positive for West Nile Virus in Phoenixville, the Pennsylvania Department of Environmental Protection announced on Wednesday.

In total, 71 new positive samples were announced throughout the state Wednesday, the largest announcement yet this year.

There were five samples in Bucks County, three in Chester County, four in Delaware County, and eight in Montgomery County that tested positive.

The other Chester County positive sample was found in Tredyffrin Township.

The Phoenixville samples were found at an undisclosed location, although generally “mosquito pool” is the most detail that is released.

The positive samples could be seen as disconcerting, as Phoenixville was only recently sprayed with insecticides for West Nile Virus control on July 16.

Officials have not yet said if there will be additional spraying after the latest positive tests.

Residents in Phoenixville previously expressed concerns about the spraying of Permanone RTU, citing environmental risks.

The Chester County Health Department maintained that the chemicals were sprayed in safe quantities.

West Nile was first confirmed in Pennsylvania in 2000 when it was found in a horse, mosquitoes, and birds.

There have been nearly 40,000 cases of West Nile in the United States since then, and 119 deaths, according to the Centers for Disease Control.

There has only been one cases of West Nile in a human reported in Pennsylvania in 2015, although many western states have had more positive tests.

Positive bird tests are much rarer than positive mosquito tests. The DEP urges all residents to report dead bird sightings.
