You should probably include war as another resource-depleting event which amplifies the effects of an epidemic.
War also has a way of throwing lots of stressed people together under unsanitary conditions. Soldiers, refugees, people in bomb shelters, etc.
The canonical example of a war coinciding with a pandemic is probably the 1918 Spanish Flu, which killed more people than WWI did.
