According to the Department of Public Health, the St. Louis area is home to more than 50 different species of mosquito.
He added that while most people do not become ill if they are bitten by a mosquito carrying West Nile, older people are more at risk.
"The two pools, or two trap sites that were positive, were found within the City of Kitchener, but really what it means is that conditions are right anywhere across the region", Miller said.
Most people infected with the virus don't show symptoms, but those who have a reaction may experience fever, nausea, headaches and muscle aches for a few days or weeks. The Centers for Disease Control and Prevention say that one in 150 people infected develop a serious illness that affects the central nervous system.
"It's a good reminder this is the time of year that we have to be concerned about West Nile regardless of where the traps are and really take precautions for ourselves".
Mosquitoes tested at various locations, including Hartford's Keney Park, have tested positive for the West Nile Virus this year. The sample was confirmed to be West Nile Virus positive by the lab at the Montana Department of Public Health & Human Services in Helena.
Since 1999, when the virus was first detected in CT, cases have cropped up ever year.
Health officials say the virus has been detected in 169 mosquito samples from across the state. The health department will also continue spraying pesticides until this year's first "freezing" temperatures.
To protect yourself from the disease, experts recommend wearing insect repellent, avoid going outside between dawn and dusk which are peak mosquito feeding times, and to wear loose clothing.
