In early March, the UK government supported a strategy to develop natural herd immunity, drawing sharp criticism from medical personnel and researchers.
[47] Various forecasts by Imperial College COVID-19 Response Team, made public on March 16, suggested that the peak number of cases in the UK would require between 100 and 225 CCBs / 100,000 inhabitants,[48] if proper mitigation or no mitigation strategies are put into force, respectively.
In the best case scenario, the peak caseload would require 7.5 times the current number of available ICU beds.
[47] In France, around March 15, the Grand Est region was the first to express the scarcity of CCB limiting its handling of the crisis.
[50] Assistance-publique Hôpitaux de Paris (AP-HP), which manages most hospitals in the French capital area (~10 million inhabitants), reported the need for 19 400 ICUs.
