Since October 20th, 2017, an increased number of mumps cases in college students have been reported from DC Universities. Mumps is an acute viral disease caused by a paramyxovirus. Symptoms include fever and swelling of unilateral or bilateral parotid or other salivary glands. Swelling usually peaks in 1 to 3 days, and can last 2 or more days before subsiding. In approximately one-third of cases, mumps infection may present with nonspecific or primarily respiratory symptoms, and can also be subclinical. A person with mumps is generally contagious two days before onset of symptoms to 5 days after. The incubation period is 14-18 days from the time of exposure, but can be as long as 25 days. Mumps spreads from person to person via respiratory secretions or saliva or through fomites.
Please obtain the following specimens as soon as mumps is suspected:
· Oral or buccal swab samples. Massage the parotid gland for 30 seconds and store in 2 ml of viral transport medium. Refrigerate samples at 4°C for shipment within 24 hours and ship on cold packs (store at -70°C if delayed).
· Serum in a red-top or serum separator tube for IgG and IgM testing
Detailed specimen collection instructions can be found on the CDC website (https://www.cdc.gov/mumps/lab/specimen-collect.html). It is critical to perform mumps PCR for confirming the diagnosis as serology test result can be misleading especially in previously vaccinated persons.

Reporting Cases to DOH
Suspected cases of mumps infection should be reported IMMEDIATELY to the Department of Health at (202)-442-9371 or via the DC Reporting and Surveillance Center (DCRC) on our Infectious Disease website (https://doh.dc.gov/service/infectious-diseases). Reports should be made at time of initial clinical suspicion of mumps infection. If diagnosis of mumps is considered and diagnostic testing are ordered, the case should be reported at that time. Do not wait for laboratory confirmation.
Updated guidelines from the Advisory Committee on Immunization Practices (ACIP) indicate that a 3rd dose can be recommended in outbreak settings for identified high-risk groups. Healthcare providers can consult with DC DOH to determine whether an additional vaccine dose is indicated. A fact sheet on (https://doh.dc.gov/page/disease-fact-sheets).
