"Three years ago, Laura Gaither and her family spent their summer vacation in Panama City Beach, Fla. One afternoon, while rinsing sand off her feet, the 35-year-old Alabama resident felt something biting her legs and noticed tiny black bugs on her skin. Gaither brushed them away, and later, when she described the bites to local residents, they told her that she had likely been bitten by sand flies.
Three of Gaither's five kids had been bitten, too, but she didn't worry. The marks on their legs and arms looked like ant or mosquito bites, which can cause burning and itching, but usually subside within a week.
But about two weeks later, back at home, Gaither noticed that the bites had morphed into small open wounds. They worsened over the next couple of weeks, but when she took her children to their pediatrician, "he just chalked it up to eczema," Gaither said."
