The bar chart shows the number of newly reported cases each day. The line chart shows the totals over time.
"Total cases" (blue) are the total number of confirmed infections.
"Active cases" (orange) are an estimate of the number of people who are likely to still be infected. The estimate assumes cases last 2 to 6 weeks, with a 2-day lag in reporting.
"Died" (gray) are the number of reported deaths.
The "target" dotted line represents 10 new cases per 100,000 people, reported over a 14-day period.
"Smoothed" data is the moving average of the preceding 7 days.
"Recent surge" ranks locations by the growth rate of new cases over the past 14 days.
"Current hotspots" ranks locations using both the current level of active cases and the growth rate of new cases.
Cases per capita (case numbers normalized by population size) are useful for estimating the local severity of outbreaks. Total case numbers are useful for estimating the allocation of resources and supplies.

The number of reported cases over time is an imperfect approximation of disease prevalence because it's affected by testing rates, reporting delays, and other factors. However, it's the most up-to-date data available.
Occasionally you may see a drop or sharp increase in the cumulative number of cases. This usually means that the reporting agency has changed their criteria for certifying cases and the historical time series hasn't yet been adjusted. See the latest data source update notes.
