Why are college students getting hand,foot and mouth disease?

More than a dozen students at Florida State University (FSU) are sick with hand, foot and mouth disease, an illness that's usually seen in young children. So why are college-age adults contracting the disease?The viral illness can cause fever, painful mouth sores, and a skin rash on the hands and feet, according to the Centers for Disease Control and Prevention (CDC). It usually affects kids younger than 5 years old.But it's not surprising to see cases of thedisease on a college campus, as it can sometimes affect adults, said Dr. Amesh Adalja, an infectious-disease specialist anda senior associate at the University of Pittsburgh Medical Center's Center for Health Security."Some people might escape infection as a child, and they get it at a later age," Adalja said.
