What is the basic math behind the Virus community spread mathematical modeling,and how the time variable;(in these models),interacts with knowledge (data),from computing complexity classes respective?.

I am not asking about how the virus is transmitted or how it replicates.

I am not asking about how the virus is transmitted or how it replicates, I am asking if there are some general mathematical formulas or graphs that describe the virus community spreading, the mathematical models; that could be used as counter strategy to slow the virus spread timing.
