In forest management, a controlled burn is “used for hazard reduction [to] decrease the likelihood of serious hotter fires” [W]. In backfiring strategy, “firefighters attempt to halt the advance of a wildfire (…) by burning up fuel in its path” [H].
Could the same strategy be used to fight the Coronavirus?
E.g. in my native country (Norway), most hotels are now closed. If, for the sake of the argument, we assume that 1) humans become immune after having fallen sick to the virus and 2) people under 25 do not become seriously ill, what is the counterargument to inviting people in the age group 15-25 to mass isolate in said hotels for e.g. 1 month, for the purpose of kickstarting herd immunity?
(In the meantime, they would also be off the streets, presumably posing less of a risk to the more vulnerable population, and students would have a chance of colocating.)
