Most Americans are worried about the current measles outbreak in the U.S. and believe vaccination against the disease should be required in schools, according to a new poll. In the latest Quinnipiac University survey, 69% of respondents said they are either somewhat (33%) or very concerned (36%) about the latest measles outbreak.

Measles cases have surpassed last year’s total less than three months into the year, as the outbreak in West Texas continues to spread.
