This sketch provided Saturday April 4, 2020 by the French Government Information Service (SIG) shows the transfers of patients infected with the Covid-19 virus in France. On high-speed trains fitted out like hospitals and military planes, France has moved hundreds of intensive care patients around the country in an exceptional effort to relieve congested hospitals and stay ahead of the fast-moving virus. But critics say President Emmanuel Macron waited far too long to act and that France, with one of the world's best health care systems, should never have faced this crisis to begin with.

France is evacuating 36 patients infected with the coronavirus from the Paris region onboard two medicalized high-speed TGV trains. The patients, all treated in intensive care units (ICU), are being transferred to several hospitals in Britany, as western France is less impacted by the epidemic.
