With the Disneyland measles outbreak expected to grow in the coming weeks, Bay Area hospitals and doctors' offices are preparing for new cases and a flood of questions from patients worried about getting sick. Health care providers who have never seen a case of measles also are being trained on how to recognize the illness and what to do with patients who show up in clinics or emergency rooms with suspicious symptoms. "We don't typically see measles cases, and that's required a fair amount of education of our physicians, nurses, emergency departments, so they're prepared and know what to look for," said Dr. Stephen Parodi, director of hospital operations for Kaiser Northern California.
