Mathematical modeling of the spread of the coronavirus under strict social restrictions
Mathematical Methods in the Applied Sciences, EarlyView., 2021 We formulate a simple susceptible‐infectious‐recovery (SIR) model to describe the spread of the coronavirus under strict social restrictions. The transmission rate in this model is exponentially decreasing with time. We find a formula for basic reproduction function and estimate the maximum number of daily infected individuals.
