MULTI-STATE MUMPS OUTBREAK

A mumps outbreak primarily linked to Jewish populations from New York and New Jersey continues to affect numerous states in the

Northeast. As of the end of January 2010, greater than 1,500 cases had been reported. To date, Delaware Division of Public Health (DPH)

has not investigated or confirmed any associated cases.

Background

The outbreak began in New York in June 2009. The index case returned to NY June 17, 2009 from a trip to the United Kingdom, where

approximately 7,400 cases of mumps have been laboratory-confirmed. The case then attended a New York summer camp for tradition-observant

Jewish boys, where he became symptomatic on June 28, 2009. Subsequent camp attendees and staff members became infected with mumps and

transmission continued in multiple locations when the camp attendees returned home. The outbreak has primarily affected the

tradition-observant Jewish community, with less than 3% of cases occurring among persons outside the community. This outbreak is also

occurring among members of the same population in Israel.

Current Concern

Mumps transmission is a current concern due to the onset of Passover (March 30^th through April 5^th), which may

offer further opportunities for transmission as people from the Jewish faith travel for this religious observance.

Recommendations for Providers

• Healthcare providers with patients in any Jewish community should ensure that these patients, including both children and adults, areup to date with measles-mumps-rubella (MMR) vaccine.The second dose of MMR vaccine for children may be administered as early as 28 days

  following the first dose.

• Healthcare providers may consider offering a second dose of MMR vaccine to adults who have received one dose.
• Healthcare providers who have contact within the Jewish community should ensure that they themselves and ALL staff are immune tomumps in accordance with ACIP recommendations

  http://www.cdc.gov/vaccines/recs/provisional/downloads/mmr-evidence-immunity-Aug2009-508.pdf or receive two doses of MMR vaccine.

• Persons with suspected mumps should be isolated for 5 days after onset of parotitis and, if they visit a healthcare setting, dropletprecautions should be initiated immediately.
