How did you deduce those figures? 50% of 100 is 50. 70% of 50 is 35.

Meaning: 1) 50 out of 100 people were infect, 2) 35 of which would die, 3) leaving 50 who didn't get infected, 4) leaving 15 who survived.

Probably by inferring "up to half of the <living> population has been infected at some point".

In your version, only a quarter of the <living> population has been infected at some point since you have 15 infected out of 65 living people.

Ah, I see it now. Apologies!
