Covid is new, but infectious disease isn't and pandemics aren't. Covid models are just epidemiology models with a given set of covid specific input parameters.

Covid is new, but infectious disease isn't and pandemics aren't. Covid models are just epidemiology models with a given set of covid specific input parameters. If a climate model doesn't work with a certain set of unpredictable input parameters, that means the model is either broken or irrelevant. Same for these covid models. Don't confuse the data for the algorithm.
