West Nile Virus activity has increased across North Carolina. In Mecklenburg County, there are two confirmed human cases of WNV. There are four confirmed human cases in North Carolina.

“The increase is concerning as the state averages two cases of WNV by the end of August,” Mecklenburg County officials said.

“I know this is a great time of year to be outdoors, but we want to make sure the public is taking caution and protecting themselves. When you’re outdoors, use mosquito repellent. Take note of any standing water around your home and empty those containers as they can be a breeding ground for mosquitos. Enjoy the weather, but be cautious,” said Dr. Raynard Washington, Public Health director, in a written statement.

While the majority of people who become infected with WNV usually experience either no symptoms or a mild, flu-like illness, about 20 percent of infected people will develop a fever with other symptoms such as headache, body aches, joint pains, vomiting, diarrhea, or rash, health officials said.
