Contains fulltext : 136840.pdf (publisher's version ) (Open Access), 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 toevidence 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.

Item does not contain fulltext, We report a large scabies outbreak occurring in Tilburg, Netherlands, which affected several different healthcare settings that provide care to the elderly and the mentally disabled. The outbreak demonstrated how the complex system of care provision to vulnerable groups facilitated extensive scabies transmission among multiple linked healthcare settings and the community.
