how covid grow and what is a formula? These three people together infect 9 other people. These nine people together will infect 27 people. What is this Meaning? The increase in cases becomes faster over time! This growth in numbers is called exponential growth. For example, in New York City during April 2020, approximately 3,354

laboratory-confirmed COVID-19 cases were reported to the NYC Department of Health and Mental Hygiene (DOHMH). We can write a very simple formula of the whole population according to the condition of the disease as follows: If (N) is the total population; (S) populations that can catch the disease; (I) the patient population; Name (R) an improved or dead population, then we come to the following simple relation: N = S + I + R
