Portuguese Prime Minister Antonio Costa has said that authorities in one of the world's most vaccinated nations may bring back some measures to stop the spread of Covid-19 in the run-up to the holiday season as infections soar across Europe, reports Reuters.

The number of new cases has been gradually rising over the past month in Portugal, reaching a two-month daily high of 1,816 infections on Saturday.

“We must try to act now so we can reach the Christmas period with less fear,” Costa told reporters on the sidelines of an event in central Portugal. “The later we act, the greater the risks.”
