“…We used an online questionnaire (Questback), publicised largely through social media, and active from 4 May to 4 June 2012, to collect information from party attendees regarding demographics, vaccination status, party-related activities (see Table 1), mumps history, and symptoms of mild upper respiratory illness/ mumps-like illness within 25 days of the party (the maximum incubation period) and also at the time they completed the questionnaire [7]. We defined cases as respondents with self-reported mumps (swelling of one/both cheeks with symptoms lasting ≥ two days) within 12 to 25 days after the party (the minimum and maximum incubation period), i.e.…”

We describe a mumps outbreak in a highly-vaccinated population attending a party at a youth club. In a retrospective cohort study with 60 of approximately 100 participants responding, vaccination status was verified for 58/59 respondents, of whom 54 were vaccinated twice and four once. The attack rate was 22% (13 cases, all vaccinated), with smoking at the party (risk ratio (RR) 3.1; 95% confidence interval (CI): 1.6-6.0, p=0.001) and age ≥21 years (RR 4.7; 95% CI: 2.1-10.2, p<0.0001) as risk factors for disease in the binominal regression analysis. Mild upper respiratory illness was also highly prevalent in those who did not meet the mumps case definition (n=46) after the party, suggesting that mumps virus infection may cause mild disease in vaccinated individuals. Our investigation adds to evidence that crowded social events and smoking may facilitate spread of mumps virus among vaccinated populations, with waning immunity playing a role. The suggestion that mumps virus infection in vaccinated individuals may manifest as mild upper respiratory illness could have implications for transmission and warrants further investigation.
