Dauphin Co. officials report West Nile Virus (WNV) infected mosquito samples have been found in the City of Harrisburg as well as Derry and East Hanover townships.
A press release from the county’s WNV Control program noted thus far nine virus-positive samples have been collected this year.
WNV-infected samples have also been found in Jefferson Twp., Highspire and Middletown boroughs and Swatara Twp. The release also noted no human cases of WNV have been reported this year in the county.
The county’s WNV Control Program is increasing surveillance and control measures throughout the county.
Certain species of mosquitoes carry WNV, which, when transmitted to people, can cause West Nile encephalitis, an infection that can result in an inflammation of the brain. Symptoms of WNV include fever, headache, body aches, nausea and sometimes swollen lymph glands or skin rash. According to the Centers for Disease Control and Prevention (CDC), all residents of areas where virus activity has been identified are at risk of getting West Nile encephalitis.
