My reading of that was that "up to 70% mortality rate" refers to specific groups. That is, mortality might be 20-30% for adults, but 70% for infants, or something to that effect.

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.

The death rate is likely to be far lower in places where the disease is endemic. People will evolve partial immunity, and the pathogen may evolve to be less deadly since it's rarely advantageous to kill the host.
"In parts of northeast Thailand, up to half of the population has been infected at some point"
That would mean that, out of every 100 people born, 75 would get infected, of which 50 die, leaving 25 who never got infected and 25 who survived.
That would mean this disease kills half of those born. Yet, this disease, which has visible symptoms, isn't well known? => I expect that "up to 70 percent" is based on an exceptional and small sample (for comparison: under five child mortality rate is 1:6 in Angola, more like 1:10 in south east Asia)
