Calculations

Active
The number of active cases is the number of confirmed cases minus the number of deaths minus the number of recovered cases.
Mortality
The number of deaths divided by the number of confirmed cases - if there are more than 1,000 confirmed cases in a country, more than 100 on a ship or 10,000 cases world-wide - otherwise "n/a".
Per 100,000 capita
The ratio is calculated by the absolute number of cases divided by the estimated population multiplied by 100,000.
