We describe 27 confirmed cases (median age: 33 years (range: 22\u201351); all males), with an earliest symptom onset date of 29 April. Almost all cases (n\u202f=\u202f25) live in the Lisbon and Tagus Valley health region. Most cases were neither part of identified transmission chains, nor linked to travel or had contact with symptomatic persons or with animals, suggesting the possible previously undetected spread of monkeypox.<\/jats:p>","DOI":"10.2807\/1560-7917.es.2022.27.22.2200424","type":"journal-article","created":{"date-parts":[[2022,6,3]],"date-time":"2022-06-03T10:16:31Z","timestamp":1654251391000},"update-policy":"https:\/\/doi.org\/10.2807\/1560-7917.es.crp2020","source":"Crossref","is-referenced-by-count":177,"title":["Ongoing
