I would leave.
Dear Friend,
I wish I could stay in town and help the town. I just dont want to get the plague and die like everyone else. If you want to come with me, I am going (Write a place). So if you want to come with me I would be glad to have the company. You know that if we still run now the plague will soon catch up to us where ever we go.
With Love,
(Your Name)
P.S. Hope to see you again.
