Dr. Rachel Hailey, with Lee's Summit Medical Center, provides tips on how to prevent the spread of measles.

"Cleaning just about anything you can think of is a good idea," Dr. Hailey says. "Most importantly, if you think you may have been exposed, don't just show up at the doctor's office. We do want you to get checked out, but call the doctor's office or ER first and say "I think I've been exposed to measles", so we can take the precautions to protect other patients."
