Of 18 suspected cases identified, 14 were included in this study. Laboratory results confirmed mumps virus as the cause and further sequencing identified genotype G. Our findings highlight that even with a high MMR vaccine coverage, mumps outbreaks in children and young adults can occur. Since most of the cases had documented immunity for mumps, we hypothesise that waning immunity or discordant mumps virus strains are likely explanations for this outbreak.<\/jats:p>","DOI":"10.1017\/s0950268821002028","type":"journal-article","created":{"date-parts":[[2021,8,27]],"date-time":"2021-08-27T06:49:07Z","timestamp":1630046947000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":15,"title":["Mumps outbreak among fully vaccinated school-age children and young adults, Portugal 2019\/2020"],"prefix":"10.1017","volume":"149","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9999-8402","authenticated-orcid":false,"given":"Mariana","family":"Perez Duque","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana","family":"San-Bento","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lourdes","family":"L\u00e9on","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paula","family":"Cust\u00f3dio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Anjos","family":"Esperan\u00e7a","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Jo\u00e3o","family":"Albuquerque","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Nascimento","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sooria","family":"Balasegaram","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rita","family":"S\u00e1 Machado","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2021,8,27]]},"reference":[{"key":"S0950268821002028_ref15","doi-asserted-by":"publisher","DOI":"10.1111\/1348-0421.12576"},{"key":"S0950268821002028_ref2","unstructured":"2.
