Leviticus 13:46 "All
the days wherein the plague shall be in him he shall be defiled; he is unclean:
he shall dwell alone; without the camp shall his habitation be."
History is full of plagues
that wiped out families, communities, and swept through countries. If we want
to write a historical novel, we can pick either the period or the epidemic and
follow the narration to flesh out the plot.
We don’t have to restrict
ourselves to history. If we want to write a contemporary story, we can make up
a disease. We could even use a known disease and imagine what would happen if
it suddenly got out of control.
