The New Jersey Department of Health (NJDOH) has reported 13 measles cases year-to-date in 2019. Of the 13 cases, there are 11 outbreak cases–7 in Ocean County residents and 4 in one Monmouth County household. This household has a direct epidemiologic link to the outbreak community in Ocean County.
Between October 2018 and January 2019, the NJDOH and local health officials worked together to investigate an outbreak of measles in Ocean County. A total of 33 outbreak-associated cases were identified, including 30 confirmed cases in Ocean County residents and 3 cases in one Passaic County household that had a direct epidemiologic link to the outbreak community.
As of January 16, two incubation periods (a total of 42 days) had passed from the last day the last known case was infectious. Because no new cases were identified during that period, the first Ocean County outbreak was considered over.
However, on Mar. 15, the second Ocean County measles outbreak was declared.
