90% dead is the claim.
Yes, there will be people who die due to medicaal conditions.
And yes, small towns and villages can take in people who are willing to work for their survival.
A lot of people would die, but no where near 90% of the population in the first year.
And as the people keep coming, what then? Turn them away once the town has become filled up? They can only absorb so many you know.
What will be their protection against disease carriers they come in contact with? Diseases such as typhoid, cholera, yellow fever, etc.....?
