History of the Peloponnesian War

Strong and weak constitutions proved equally incapable of resistance, all alike being swept away, although dieted with the utmost precaution.

By far the most terrible feature in the malady was the dejection which ensued when anyone felt himself sickening, for the despair into which they instantly fell took away their power of resistance, and left them a much easier prey to the disorder; besides which, there was the awful spectacle of men dying like sheep, through having caught the infection in nursing each other. This caused the greatest mortality.

On the one hand, if they were afraid to visit each other, they perished from neglect; indeed many houses were emptied of their inmates for want of a nurse: on the other, if they ventured to do so, death was the consequence. This was especially the case with such as made any pretensions to goodness: honor made them unsparing of themselves in their attendance in their friends' houses, where even the members of the family were at last worn out by the moans of the dying, and succumbed to the force of the disaster.
