There have been three human cases of West Nile virus in the county this year.
The Allegheny County Health Department will treat for mosquitoes in several Pittsburgh neighborhoods where they have tested positive for West Nile Virus.
Also, one positive mosquito pool with 11 mosquitos tested positive for WNV in a pool located in West Brant.
A county resident was released from a local medical facility after being admitted for West Nile virus-like symptoms.
According to an announcement from Gov. Dannel P. Malloy's office, the rates of mosquitoes carrying West Nile have been much higher this year. The Health Unit has been trapping and testing mosquitoes since June. In 2012, the last time Dallas County saw a major outbreak of West Nile virus, 398 residents contracted the virus and 21 died.
The mosquitos get the virus by feeding on infected birds. Of those who show symptoms, most will experience mild illness, including fever, headache, body aches, nausea, vomiting and rash on chest, stomach or back.
Use insect repellent containing DEET when outside.
Remove standing water around the home at least once a week to reduce mosquito breeding grounds.
