Across the country, West Nile virus cases are up four times over what is normal for this time of year. The Center for Disease Control reports it’s one of the largest outbreaks ever. And in the Carolinas, the numbers are up and expected to rise as the mosquito season continues.
Experts can’t put a finger on exactly why there are so many cases this year. But they speculate that the mild winter, early spring, and hot summer have stimulated mosquito breeding. And thus increased the spread of the virus.
