A 10-year-old girl swims in the Brazos River and Whitney Lake in Bosque County near Waco on Labor Day weekend, according to CNN affiliate KWTX-TV.
Then, on September 8, the girl "started having a headache and was quickly followed by a fever," according to a Facebook page created to support the girl. Her family thought it was a viral infection at first, but after visits to the family doctor and the girl who was having trouble sleeping, the family knew something was wrong.
"She was inconsistent, unresponsive and quickly swept away and taken to the EP," the family wrote on the girl's Facebook page.
The girl was then flown to cook for the Children's Health System in Fort Worth, where she has a spine. "For this to happen to her when there were so many other people in the same waters on the same days, we just don't understand why she was."
