Thank you for your input and replies, everyone. freedom is right, it may be disease that brings us down, not a bullet. Remember the Plague of Europe…thousands died because of rats and their fleas carrying it in unsanitary conditions.

And I think typhoid can be spread by flies carrying it from exposed sewage/waste–and by drinking polluted water. My grandfather had it in the early 1900s here in the US. Came home from the hospital a skeleton…my Dad, as a toddler, was afraid of him. But he did survive. Few will these days.
