“Most infections have been reported, to date, in Lisbon and Vale do Tejo, but there are already cases in the other regions (North, Center, Alentejo and Algarve)”, adds the entity led by Graças Freitas in a note published on the website.

All confirmed infections are in men between the ages of 19 and 61, most of whom are under 40, says the DGS, adding that the identified cases remain “under clinical follow-up” and are “stable”.
