Chile: Santiago goes back into lockdown despite 60% #coronavirus vaccination rate

As of the early hours of this Saturday, 12th June 2021, Santiago de Chile has once again entered quarantine. The entire region begins with the mobility restriction measure when 57.8% of the country’s target population has completed their covid-19 vaccination schedule, but ICUs are on the brink of collapse.

According to the latest figures provided by the Undersecretary of Health, Paula Daza, the occupation of critical beds reaches 96% nationwide. But the vast majority of seriously ill patients are not immunized and there is a worrying decrease in the age of patients admitted to critical beds. Patients under 50 years of age in ICUs have tripled compared to the worst moment of last year, according to ICOVID, an initiative led by the University of Chile, the Pontificia Universidad Católica de Chile and the University of Concepción based on official data . The deaths reach 38,685, between confirmed and suspected.
