Mumps Outbreaks

In 2006, the United States experienced a multi-state outbreak involving 6584 reported cases of mumps. This resurgence predominantly affected Midwestern college students with the highest attack rates occurring among those living in dormitories. In the following two years, the number of reported cases returned to usual levels, and outbreaks involved fewer than 20 cases.

However, beginning in July 2009, the largest U.S. mumps outbreak since 2006 has occurred. The index case was an 11-year-old boy who had returned on June 17 from the United Kingdom where an ongoing mumps outbreak involves more than 4000 cases. Because of the potential for more extensive disease transmission, efforts should be made to heighten surveillance for mumps and assure that children and adults are appropriately vaccinated against this disease.
