Transcript for Measles Cases Spread to New States
We turn to that growing measles outbreak. It's spread to three more states, Delaware, Michigan and Nevada. Now 121 reported cases in 17 states so Dr. Richard Besser is back with us. Boy, this shows no signs of slowing down. I find this worrisome. This is a disease we knocked out in 2 thousand thou and yesterday I spent the day with one of the heads of measles control at CDC and saying there are more cases in January than any one month in the past 20 years. What's most surprising? Most people think about measles as a disease just of children but that's not what they're seeing here. California's had the most cases and looked at their data, 59% are in people 20 and older. A lot of adults are getting measles. So what should adults do about this? Most of us grew up and had the vaccine. A lot of people don't know. They don't have shot records. If you're born before 1957, you don't have to worry, everyone back then had measles. Anyone else, you can ask your doctor to do a blood test to see if you're protected or ask for another vaccine. If you're not sure get the vaccine or get tested. You don't want to be out there and just not know. If so you're at risk. Rich will be on Twitter throughout the morning to answer all of your questions.
