" Once ‘free’ in the streets, what then? Fear and panic could destroy the city as much as plague itself. Many of the doctors fled, along with the rich and powerful; quacks preyed on the poor with their neverfail miracle drugs. Churches and conventicles and synagogues were empty. Neighbours informed against each other. People lied to each other – and to themselves. (It’s just a headache. Just a little bruise. I’ll feel better if I go for a walk.) Worse – there were stories of infected people deliberately concealing their telltale ‘tokens’ and going out into the streets trying to infect others. "

― Daniel Defoe , A Journal of the Plague Year
