The phrase "flattening the curve" is used frequently these days by epidemiologists to describe various measures to keep the daily Covid19 cases at a manageable level, in order to avoid overwhelming our healthcare system.
It has also brought mathematical modeling of the pandemic to the public's attention. According to a Youtube channel, 3Blue1Brown, a simple yet realistic simulation known as the SIR model can help us gain some fundamental understanding of how the coronavirus spread in our society. And more importantly, by focusing on several critical parameters, we can contain the pandemic more effectively, delay its spread, and prevent unnecessary suffering.
For example, positive changes in personal hygiene - frequent handwashing, mouth covering when sneezing and coughing, and zero face touching - can drastically reduce the probability of infection and flatten the curve. Other measures, such as social distancing, avoid centralized gathering, identifying and isolating confirmed cases, and avoiding cross-community travel, are among the most effective community approaches.
