Dr. Oz says there's a straightforward advantage to staying infection-free in a hospital. "You're in an environment that has sick people in it who have infections themselves," he says. "It's so easy to spread to you."

• Ask people to wash their hands before touching you.
• Keep hand sanitizer by your bed.
• Try to avoid bacteria-promoting items, like flowers and jewelry.
• Ask doctors to clean their stethoscopes. "Did you ever think where the stethoscope was before he examined you?" Dr. Oz says. "It was on someone else's chest, and that same bacteria gets carried to you."
• Clean television remotes.
• Ask a doctor to remove his tie, or else tuck it into his shirt. "How many men here have ever washed their tie?" Dr. Oz says. "Nobody. No one washes a tie. Doctors don't either."
