U.S. Multi-state Measles Outbreak, 2014-2015 (10/30/2015)
From January 1 to October 23, 2015, 189 people from 24 states and Washington DC were reported to have measles*. Most of these cases were part of a large, multi-state outbreak linked to an amusement park in California. On 01/23/2015, CDC issued a Health Advisory to notify public health departments and healthcare facilities about this multi-state outbreak and to provide guidance for healthcare providers nationwide. No new cases related to this outbreak have been reported since March 2015. The outbreak likely started from a traveler who became infected overseas with measles, then visited the amusement park while infectious; however, no source was identified. Analysis by CDC scientists showed that the measles virus type in this outbreak (B3) was identical to the virus type that caused the large measles outbreak in the Philippines in 2014.
The United States experienced a record number of measles cases during 2014, with 667 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.
In 2015, 3 confirmed cases of measles have been reported to the New Jersey Department of Health (NJDOH):
- One in a Hudson County resident, January. This case has now recovered and no additional cases associated with this Hudson County case have been reported.
- One in a Princeton University student, February. The student has recovered and no additional cases associated with this Mercer County case have been reported.
- One in a Middlesex County resident, May. This case has now recovered and no additional cases associated with this Middlesex County case have been reported.
None of these NJ cases had any identified connection to the measles outbreak associated with Disneyland in California.
NJDOH continues to urge providers to remain vigilant for cases of measles (consider measles in persons who present with fever and rash) and would like to remind all NJ residents, health care, and public health professionals about the importance of receiving up-to-date immunizations, especially prior to international travel.
*CDC will update this data monthly.
