We track the number of new cases to show how quickly the virus is spreading.
The 7-day rolling average shows the trend in new cases. We calculate the rolling average by averaging the new cases for a particular day with the new cases for the prior 6 days.
Recent case data are less reliable, as data are still being validated. We do not calculate the rolling average for less reliable data.
The total cumulative number of cases is the running total. The cumulative total will always increase. The steep increases show times with higher numbers of daily new cases.
