"That night they didn't know," explained his aunt Michelle Pahl. "It was a 50/50 percent chance he'd make it through the night."

Experts say RMSF is rarely found in Minnesota. The Centers For Disease Control and Prevention report as few as three to seven cases in the state a year, although the wood tick that carries the bacteria is common here, according to a U of M entomologist.

"You're going to find wood ticks in much drier environments than you would find deer ticks, so wood ticks can survive in brushy areas and even (tall) grass," said Jon Oliver, a public health entomologist with the University of Minnesota who specializes in vector-borne diseases. 

He says the disease is also difficult to pinpoint - Pahl says it took doctors several days to diagnose Gino who had the telltale rash and fever.

"No one in that hospital, is what I heard, has seen a case like that," Pahl said.

While Oliver explained that it is treatable in children and adults with antibiotics. "With treatment, survival rates are good, but without treatment the disease is often fatal," he said.

Gino also has weeks of physical therapy ahead after being released from the hospital on Saturday. His family thinks he got bit in their neighborhood - a new housing development in Buffalo. 

It's important to do daily skin checks for the wood tick which can be easier to spot than the deer tick because it's bigger. The deer tick often carries Lyme disease.

Oliver said there is another known case of RMSF in Buffalo. And Pahl says doctors are also testing Gino's sister for RMSF because she had similar symptoms, but wasn't hospitalized. A neighbor of the Pahl family is also reporting their dog had a tick and is now severely ill.
