Conversation so far:
What was the Great Plague?
Outbreaks of plague were not particularly unusual events in London; major epidemics had occurred in 1592, 1603, 1625 and 1636.
What was included in this plague?
Pepys was not among the group of people who were most at risk.
He did not live in cramped housing, he did not routinely mix with the poor.
