Measles were thought to be eliminated in the U.S. in the year 2000, but they are making a swift comeback and doctors blame it on the anti-vaccination movement. Currently, Arizona has the largest outbreak in the U.S. with 22 confirmed cases at last count including many adults.  The likely carrier was a migrant worker at a detention center who exposed adults without proof of vaccination.  Dr. Stephen Lauer, pediatrician at The University of Kansas Hospital explains how serious, even deadly the measles can be and why it’s so important to have children vaccinated.
