The Pennsylvania Health Department last year ranked Bucks County as the fourth-highest number of West Nile Virus detections in the state, and thus far, there have been 49 positive cases in the county and one person infected with the virus.
According to the Bucks County Department of Health, staff has been conducting outreach, removing habitats, responding to complaints, and treating standing water for larvae since April.
The county health department has also been collecting adult mosquitoes using monitoring traps and sending them to the State laboratory for analysis of West Nile Virus and other mosquito-borne diseases.
According to the department, the data helps determine if an adult mosquito control event is necessary, which could include barrier treatments with powered backpacks, hand fogging, or utilizing a ultra-low volume (ULV) truck-mounted sprayer.
As of August, the virus has been detected in adult mosquitoes in northern, central, and southern portions of Bucks County.
As the mosquito season progresses, an adulticide treatment event may be necessary, according to the health department.
The Advance of Bucks County reported that Bucks County registered 242 positive WNV cases and one human infection.
Most people infected do not experience symptoms, but about one in five develop fever, headache and fatigue.
