The West Nile Virus has been found in Mosquito populations in St. Charles County.
Officials say the diagnosis is not a cause to panic, but suggest that people should be careful when they go outside.
Health Officials have been more active testing mosquitoes lately since floodwaters have increased their natural breeding ground.
West Nile Virus usually does not develop any symptoms but can cause a severe illness in about 1 in every 150 people.
