The number of confirmed measles cases in the United States increased by 20, according to the latest data from the Centers for Disease Control and Prevention (CDC).
From January 1 to February 13, 2015, 141 people from 17 states and Washington DC were reported to have measles [AZ (7), CA (98), CO (1), DC (1), DE (1), IL (11), MI (1), MN (1), NE (2), NJ (1), NY (2), NV (4), OR (1), PA (1), SD (2) TX (1), UT (2), WA (4)]†. Most of these cases [113 cases (80%)] 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.
The CDC reminds US travelers that measles remains a common disease in many parts of the world, including areas in Europe, Asia, the Pacific, and Africa. In the United States, most of the measles cases result from international travel. The disease is brought into the United States by unvaccinated people who get infected in other countries. They spread measles to others, which can cause outbreaks.
Before any international travel—
- Infants 6 months through 11 months of age should receive one dose of MMR vaccine.†
- Children 12 months of age and older should receive two doses of MMR vaccine separated by at least 28 days.
- Teenagers and adults who do not have evidence of immunity* against measles should get two doses of MMR vaccine separated by at least 28 days.
