Mumps Outbreak in Tulsa County, Oklahoma – Clinician Recommendations
The Tulsa Health Department (THD) and Oklahoma State Department of Health (OSDH) are investigating an outbreak of mumps in Tulsa County. Since February 2017, 8 cases of mumps have been identified among residents of Tulsa County, including 5 laboratory-confirmed by polymerase chain reaction (PCR). As of March 7, 2017, all 8 cases are individuals affiliated with a Tulsa-area business, and household mem...bers of a case. The recent onsets of cases mean transmission is ongoing and exposed, personal contacts may develop illness over the next several weeks. The majority of outbreak-associated mumps cases have a documented vaccination history of at least 2 doses of MMR; therefore, clinicians are advised to test for mumps in patients with acute parotitis even among patients with a history of MMR vaccination.
Clinicians should contact the OSDH Acute Disease Service Epidemiologist-on-Call at (405) 271-4060 (24/7/365 availability) to report suspected mumps cases that meet the following criteria:
1. Parotitis and exposure to a mumps outbreak affected area; OR
2. Positive laboratory results for mumps PCR, viral culture, mumps IgM, and IgG titers greater than laboratory cutoff values.
