Abstract
In 2017, Penn State University's campus experienced a mumps outbreak that coincided with unrelated restrictions on social gatherings. University Health Services implemented testing, contact tracing, and quarantine and isolation protocols. Approximately half of the supplied contact tracing information was usable, ∼70% of identified contacts were reached, and <50% of those contacted complied with quarantine protocol. Students with confirmed mumps reported ∼7.4 (1-35) contacts on average. Findings from this outbreak can inform future outbreak management on college campuses, including COVID-19, by estimating average contacts per case, planning capacity for testing and quarantine/isolation, and strategically increasing compliance with suggested interventions.
Highlights
Mumps is a transmissible disease caused by a paramyxovirus
Since August 2016, new students and all students living in university housing must provide proof of MMR immunization to Penn State University (PSU)
Eighty-four student cases of mumps were diagnosed through University Health Services (UHS), with an additional 32 cases in 2018
Summary
Lessons from managing a campus mumps outbreak using test, trace, and isolate efforts.
