DEP awards nearly $2.1 million in West Nile Virus grants to 26 counties

Apr 16 2014

The Department of Environmental Protection (DEP) today announced it is awarding nearly $2.1 million in West Nile Virus (WNV) Control Program Grants to 26 counties.

"These county grants ensure that mosquito populations stay in check to prevent the spread of West Nile Virus," DEP Secretary E. Christopher Abruzzo said. "Locally-based programs play an important role in protecting the public from this perennial problem."

The funding is used to cover the costs associated with surveying and controlling mosquitoes that carry WNV. DEP developed the funding proposals in consultation with county officials based on need. The grant program is funded by the General Fund.

To reduce the risk of WNV, DEP and county staff use a combination of education, source reduction and mosquito control. Mosquito control is largely done by using larval control products, such as Bti, which is derived from soil bacteria.

If necessary, man-made adult mosquito control products derived from the chrysanthemum flower are used to reduce mosquito populations when they pose an elevated risk of infecting people. Adult mosquito control products are effective in controlling mosquito populations and pose little to no harmful effect to humans, plants or other animals.

Last year DEP detected 1,213 mosquito samples, 28 avian specimens, two horses and 11 humans infected with WNV in Pennsylvania. 

In humans, the virus can cause West Nile fever and encephalitis, an infection that can cause inflammation of the brain and death. Most people bitten by an infected mosquito will never develop any symptoms, and only one person in 150 people with symptoms will develop the more serious West Nile encephalitis.

Residents are encouraged to remove all standing water from their property to prepare for mosquito season and prevent infection.
