Charleston Area Prevalence of Infections

This graph indicates the prevalence of COVID-19 in the Charleston area.

What Do These Graphs Show?

The first graphic shown is the estimated number of active COVID-19 cases over time. An “active case” means that someone was infected, but has not yet recovered or died. These are people who can transmit the virus. The second graph shows the cumulative number of cases per capita, and indicates how prevalent COVID-19 is in a community. It is a helpful metric to compare the extent of the epidemic in different localities of various size because it provides the number of cases relative to the size of each location’s population. The total number of cases can be misleading if one does not consider the population size of the geographic area being reported on.
