Area under the curve, what does it represent?
Without discussing the calculus of these functions, understanding the “area under the curve” is integral to conceptualizing these curves. The 2-dimensional shaded area below the curve will represent the total number of cases. We will designate this area as AUC. Depending on the type of curve, it will represent the total number of measured infections, mortalities, and recoveries. Hence the following formula will apply:
AUC infection = AUC mortality + AUC recovery.
In other words, the total number of people infected will be equal to the number of people who pass away added to the number of people who recover.
