About 80 per cent of people bitten by an infected mosquito don't show any symptoms at all, Miller said.
New Jersey health officials report that the state has seen its first case of West Nile virus in a human this year.
Although most people don't develop symptoms, approximately 20 percent of those infected will develop an infection known as West Nile Fever, according to the CDC.
According to the state Department of Public Health, the patients were residents of Fairfield and Newington.
The mosquito that tested positive for West Nile, came from a mosquito trap on North Market Extension in St. Clairsville, in the area near the ball fields and walking trail.

However, he has less than 32 hours to make that happens as this summer transfer window shuts on Thursday, August 9, by 5pm. It might be hard for him to get regular playing time at Chelsea this season, so sending him out on loan makes sense.
Additionally, on August 6, the Mississippi State Department of Health confirmed six additional cases of West Nile virus, bringing the state's 2018 total to 13 so far.
Officials say positive mosquito batches have been found in traps located in every community the district serves.
People older than 50 or who have weakened immune systems are at higher risk for severe illness from the virus. The federal Environmental Protection Agency said residents should "empty and scrub, turn over, cover, or throw out items that hold water, such as tires, buckets, planters, toys, pools, birdbaths, flowerpots, or trash containers".
Wear long sleeves and trousers or wear repellent to help protect yourself from getting bitten.
