The Delaware Division of Public Health (DPH) is investigating an outbreak of mumps cases among school-age children in New Castle County. As of March 3, 2020, DPH had identified nine cases of mumps as part of this outbreak, including seven confirmed cases and two probable cases.
The Delaware Division of Public Health (DPH) is now confirming nine cases of the mumps as part of its ongoing investigation of an outbreak among attendees at a February dance festival in New Castle County. An eighth person was working at another Baile Mejicano dance, held at the same location, which occurred on March 3, 2018. DPH is now recommending that anyone who attended either the Feb. 10 or March 3, 2018, dances contact their primary care physician to determine if they may have contracted mumps and if they and their family or close contacts need to receive vaccination against mumps.
