Up to 27 May 2022, Portugal has detected 96 confirmed
cases of monkeypox. We describe 27 confirmed
cases (median age: 33 years (range: 22–51); all males),
with an earliest symptom onset date of 29 April.
Almost all cases (n = 25) 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.info:eu-repo/semantics/publishedVersio
