The mumps outbreak in the United States has eclipsed 5,000 cases with two weeks left in 2016, according to data from the Centers for Disease Control and Prevention (CDC) and state health departments.


CDC data shows that through Dec. 17, 4,915 cumulative provisional cases have been reported from 46 states and Washington DC. However, the CDC numbers do not reflect the most up-to-date numbers provided by the states.

For example, CDC shows that Arkansas, the state with the most cases, has 1,900; however, the Arkansas Department of Health (ADH) puts the total at 2,270 through Dec. 20. This alone puts the national total well over 5,000.

A number of colleges and universities have been through and are currently experiencing outbreaks of mumps.

At the University of Missouri, one of the most active college outbreaks currently, school health officials put the total at 265 cases since the beginning of the Fall semester.

The last time the US has seen a mumps outbreak like this year was 2006 when more than 6,500 cases were reported.
