How do you calculate case rate?
How it’s calculated: Take the number of COVID-19 deaths in a population. Divide that by the total number of COVID-19 cases and multiply by 100. This is typically expressed as a percentage. What it means: A case fatality rate tells you how severe a disease is.
How do you calculate death rate?
death rate = deaths / population * 10n , where, deaths – Deaths measured within specified time interval for a certain population; n – The exponent and gives you the answer per every 10n people.
