That’s exactly how death rates are calculated the number of deaths divided by the number of confirmed cases, it’s calculated the same way for the flu as it is the coronavirus.
It’s estimated by some the total death rate for the corona virus to be 1% when its done, and some say between 1.5-2.5%, but ad I stated earlier the death rate has a direct correlation with what countries do as a measure to battle the virus as some countries are well into double digits death rate and some under the 5% range.
It’s also important to note the death rate will start to somewhat neutralize at the tale end of quarantining exactly like it happened in China.
But as some have tried to claim that the death rate is the same as the flu that is false as the flu has a death rate of 0.1%.
That is a flawed methodology and testing 1% of the population is a statistically insignificant sampling.
For simplicity, let`s use round numbers.
Let`s say at the time we hit 500 deaths, 100,000 have been tested and 10,000 people have been found to be infected. The death rate would be 5%.
Let`s say at the same time of 500 deaths, 500,000 have been tested and 50,000 have been found to be infected. The death rate would be 1%.
Let`s say at the same time of 500 deaths, 1,000,000 have been tested and 100,000 have been found to be infected. The death rate would be 0.5%.
All of these examples are for the exact same time and number of deaths. The only variable is the capacity to test.
When testing is lacking and lagging, the statistics are not accurate.
The extreme example of this is at the beginning of the testing.
People are dying before they can even do the testing so there is a time when the number of known infections is double the number of deaths. Does this mean the death rate was 50%?
As testing catches up, this number goes down.
Right now testing is still severely lacking and lagging as Ontario is just now approaching 1% of the population.
The death rate is not going to neutralize, it is the statistics that are going to catch up to reality.
The death rate will go down when treatments improve.
