A new warning about West Nile virus.
Health officials have confirmed several mosquitoes in Allegheny County tested positive for West Nile.
The mosquitoes were collected in Pittsburgh's Beltzhoover and South Side Slopes neighborhoods and the borough of Mt. Oliver.
The county's last human case of West Nile virus was reported in September of 2022.
If you get bitten, experts say most people infected with the virus don't feel sick. One only one in five people will develop symptoms like fever, headache, or vomiting.
The County health department will continue to monitor mosquito traps in the area.
