The Allegheny County Health Department has confirmed that mosquitoes found July 6 in Point Breeze, the North Side, and Wilkinsburg carried the West Nile virus.
West Nile virus is the leading cause of mosquito-borne disease in the United States. There is no vaccine or medication to combat it.
Though there have been no reported human cases of the West Nile virus this year, there were three cases reported in 2021 in Allegheny County.
County health department spokesman Neil Ruhland said that every year the department places traps in stagnant water, from which they are able to collect mosquitos and test them for the virus.
The virus is hard to detect, as most people who are infected don’t feel sick. The department said in a press release that only 1 in 5 people infected develop a fever or other symptoms, including a headache, joint pain, rashes, and nausea. Less than 1% develop a serious illness.
Residents who have developed symptoms, or believe that they or someone that they know has contracted West Nile virus, should consult a health care provider for diagnosis and treatment.
Epidemiology supervisor Jennifer Fiddner suggested that residents protect themselves from the virus by getting rid of standing water in yards, making sure open windows and doors have screens, and — most effectively — using insect repellent on exposed skin.
If cases develop in the future within the areas where West Nile was found, the county health department will take action to reduce the mosquito population.
Though these efforts will not be centered solely in the communities where the virus has been found, the county health department will be working with the Pennsylvania Department of Environmental Protection to “assess any threats to public health.”
Residents can report mosquito breeding sites on both private properties and public areas to the county health department’s Vector Control Program by completing its online form or calling 412-687-2243.
