Before revision:  This approach yields a time-varying reproduction number that is continuously adjusted , based on infection information through a negative-feedback term that is similar to Michaelis-Menten and Hill functions in chemistry and molecular biology.
After revision:  This approach yields a time-varying reproduction number that is continuously adjusted , based on infection information through a negative-feedback term that is equivalent to Holling type II functions in ecology and Hill functions in chemistry and molecular biology.
