Recent findings have confirmed the presence of West Nile Virus (WNV) in mosquito populations across several neighborhoods in Allegheny County, including Wilkinsburg, Schenley Park, Mt. Washington, Beltzhoover, Mt. Oliver, and Hazelwood . The detection of this virus raises public health concerns as it is primarily transmitted to humans through mosquito bites. Although the last reported human case occurred about a year ago, vigilance is necessary to prevent potential outbreaks .
Samples found to have the virus were taken July 8 from Wilkinsburg, Schenley Park, Mt. Washington, Beltz hoover, Mt. Oliver and Hazelwood.
West Nile virus is the leading cause of mosquito-borne disease in the nation, according to the Centers for Disease Control & Prevention.
It is most commonly spread to people through insect bites. Cases occur during mosquito season, which starts in the spring and continues through fall.
Symptoms include fever, headache, body aches, vomiting, diarrhea or rash.
There are no vaccines to prevent or medicines to treat West Nile in people, the CDC reports.
The health department's Vector Control Program collected samples across the county on July 8, and the samples taken in Wilkinsburg, Schenley Park, Mt. Washington, Beltzhoover, Mt. Oliver, and Hazelwood tested positive for West Nile Virus.
"Generally, the species of mosquitoes that carry West Nile Virus are active from dusk to dawn," explained ACHD Vector Control Specialist Nicholas Baldauf. "Residents can prevent mosquito bites by using insect repellent on exposed skin or choosing to wear long sleeves and pants. Both methods are effective at reducing or eliminating the possibility of getting a mosquito bite."
West Nile Virus is the leading mosquito-borne disease in the U.S. and is spread to humans through bites from infected mosquitoes.
Most people infected with West Nile do not feel sick or show symptoms. The health department says only one in five people will develop a fever and other symptoms such as a headache, body aches, joint pains, vomiting, diarrhea or rash.
Less than one percent of infected people develop serious illness.
The health department says there are no vaccines or medications to prevent West Nile, and says residents should be cautious and aware of mosquito formations.
The Allegheny County Health Department has emphasized the importance of preventive measures for residents. Recommendations include utilizing insect repellent and wearing protective clothing such as long sleeves and pants when outdoors . Such precautions are vital during warmer months when mosquito activity peaks and the risk of transmission increases.
In conclusion, while current data indicates a low incidence of human cases in Allegheny County since last year, the detection of WNV in local mosquitoes necessitates heightened awareness and proactive public health strategies to mitigate risks associated with this vector-borne disease.
