Over the years, Dr. Oz says MRSA has traditionally been found in hospitals, but now, you can contract it in homes, schools, locker rooms and health clubs.

"The number of us who have MRSA living on our skin already, which earlier in this decade was maybe 1 percent at most, is now at least 10 times higher than that," Dr. Oz says.

Athletes are at higher risk than most. Since 2006, 33 professional football players have been infected by MRSA.

"This thing really gets the attention of medicine because this is a kind of bacteria that we can't kill anymore," Dr. Oz says. "It's outsmarted us, and it keeps ahead of us."
