The above graph shows new cases, i.e. the number
of new cases we have seen.
Cases is total COVID-19 cases; cases per 100,000 is cases per 100,000 people; cases 14-day per
100k is the total number of cases over the last 14
days, added together, then multiplied by 100,000, then divided by the
population. New cases is the number of cases we have had per day on average over the last seven
days. Growth is the increase in cases compared
to the previous number of cases; the number is a 7-day
average. Doubling days is the number of days it will take for
cases to double at the current growth rate (calculated),
or the number of days in the past we have had half the current number
of cases (actual).

The number of actual COVID-19 cases and deaths are almost certainly higher
than these figures.
