The Centers for Disease Control and Prevention (CDC) reports that from Jan. 1, 2015 to Feb. 6, 2015, 121 people from 17 states and Washington, D.C. were reported to have measles [AZ (7), CA (88), CO (1), DC (1), DE (1), IL (3), MI (1), MN (1), NE (2), NJ (1), NY (2), NV (2), OR (1), PA (1), SD (2) TX (1), UT (2), WA (4)]. Most of these cases (103 cases or 85 percent) are part of a large, ongoing multi-state outbreak linked to an amusement park in California.
The United States experienced a record number of measles cases during 2014, with 644 cases from 27 states reported to CDC's National Center for Immunization and Respiratory Diseases (NCIRD). This is the greatest number of cases since measles elimination was documented in the U.S. in 2000.
