Hello everyone, in this problem, the first part of the problem, you need to find the cause -specific morality rate from s .h .e.
00:14
Colli in 2014.
00:16
So the cause -specific morality is the rate is the number of deaths from a specific cause for these number of persons years at risk.
00:56
So here the specific cause is sickness with e .coli.
01:00
So you can denote this by cmr.
01:04
So it would be the number of deaths by e .coli that is 128 divided by total population that is 90158, sorry 150 multiplied by this person.
01:23
So simplifying this, we have this value to be 141 .99.
01:28
Now let us move on to the next part of the problem where we need to find the case fatality rate.
01:34
So case fatality is the proportion of death from a certain disease compared to the total number of period diagnosed with the particular disease.
02:19
So we denote ratio by cfr.
02:22
Cfr will be equal to number of deaths by e .coli is 128 divided by number of people diagnosed by e .coli is 274.
02:32
Upon dividing, we have the value to be 0 .47...
