Yes, managing a pandemic requires a structure in which everyone speaks with the same voice. It takes a degree of centralization, but that does not exclude adapting to local realities. In fact, the marching orders cannot apply in the same way in a province with no cases of the virus as in another with a crisis.
So I believe we need a mixed model, but one with good central and coordinated management. Public health messages must be consistent. We must say generally the same thing, but then tailor the message to local realities.
