According to official data released on Monday, the number of Coronavirus infections in Spain has increased by 32,607 since Friday, an increase of 85 percent over the previous weekend’s increase, as the Delta variety causes a surge among unvaccinated young people.

The overall 14-day infection rate increased to 204 cases per 100,000 persons on Monday, up from 95 instances a week earlier, according to the report, with 640 cases among 20-29 year olds.

Other European countries, including as France and Portugal, have made immunization available to all adults, while Spain has worked via age groups, leaving the majority of young people unvaccinated.

Some 89% of Spaniards over 40 have received at least one dose, compared with 14% of 20-29 year old.

“Right now we are in a delicate situation in terms of transmission, but at least it is not being reflected in terms of severe cases,” Health Emergency Coordinator Fernando Simon told a news conference.

Hospital admissions have so far been largely unaffected and national intensive care occupancy stands at less than 7%.

Before infections began ticking up in mid-June, contagion had fallen steadily since April, prompting the government to lift a requirement to wear masks outdoors and ease other restrictions.

But as authorities scramble to curb fresh outbreaks, several regions, including Catalonia and Cantabria, are considering reimposing restrictions on nightlife and social events.

Monday’s update brought the total tally of coronavirus cases to 3,866,475 and the death toll rose by 23 to 80,934.
