Omicron currently responsible for 90% of infections in Portugal

The Omicron variant is currently responsible for 90% of all infections in Portugal. In the week before Christmas, it was most prevalent in the Lisbon/ Vale do Tejo region, while the Algarve was still dominated by Delta (this latter aspect is already changing in line with the rest of the country). This morning’s meeting to update the government on ‘experts’ thinking’ has heard that the greatest dissemination of Omicron has been registered in the 20-29 year age group.
