Responding to a Mumps Outbreak Impacting Immigrants and Low-English-Proficiency Populations

This study sought to examine outbreak response-associated costs, lessons learned, and challenges encountered during a mumps outbreak in Chester County, Pennsylvania in March-July 2018. The outbreak primarily affected an immigrant community, some of whom spoke little or no English and were uninsured and/or undocumented. This necessitated an urgent response from the Chester County Health Department, which implemented a variety of public health interventions, including outreach to local health care providers and the execution of vaccination clinics at 2 local mushroom farms where case contacts worked. The authors conducted semistructured interviews with individuals directly involved in the response to the mumps outbreak and analyzed outbreak response-associated cost data.
