title: Mumps outbreak - New York, New Jersey, Quebec, 2009.
abstract: Mumps is a vaccine-preventable viral infection characterized by fever and inflammation of the salivary glands and whose complications include orchitis, deafness, and meningo-encephalitis. In August 2009, CDC was notified of the onset of an outbreak of mumps in a summer camp in Sullivan County, New York. The outbreak has spread and gradually increased in size and is now the largest U.S. mumps outbreak since 2006, when the United States experienced a resurgence of mumps with 6,584 reported cases. On August 18, public health departments in Sullivan County, New York state, and CDC began an investigation into the mumps outbreak, later joined by departments in New York City and other locales. As of October 30, a total of 179 confirmed or probable cases had been identified from multiple locations in New York and New Jersey, and an additional 15 cases had been reported from Canada. The outbreak primarily has affected members of a tradition-observant religious community; median age of the patients is 14 years, and 83% are male. Three persons have been hospitalized. Although little transmission has occurred outside the Jewish community, mumps can spread rapidly in congregate settings such as colleges and schools; therefore, public health officials and clinicians should heighten surveillance for mumps and ensure that children and adults are appropriately vaccinated.
