There is a reason that "flesh-eating bacteria" is currently #5 on Google Trends right now (sandwiched between "josh hamilton" and "gcb," for which I cannot say the same), but it might scare you enough to never, ever go near a lake again, ever.
Within a week of cutting her calf in a zip-lining accident on vacation in Carrollton, Georgia, a 24-year-old University of West Georgia graduate student named Aimee Copland has lost her left leg to a bacterial infection known as necrotizing fasciitis and may lose her other leg as well as both her hands. She is conscious, neurologically sound, and her lungs are improving, but she remains in critical condition and is completely reliant on a ventilator.
Doctors believe the bacteria that infected Copland resided in a nearby Carrollton freshwater lake called Little Tallapoosa. Although the infection is extremely rare, its mortality rates are upward of 60% according to a 2010 report. People are significantly more susceptible if their immune system is currently weaker than normal. Copland's friends and family are rallying for her improvement with a blood drive fundraiser and a Facebook page.
