During the 1300s, this epidemic struck parts of Asia, North Africa, and Europe. Almost a third of the people in Europe died of it. Unlike catastrophes that pull communities together, this epidemic was so terrifying that it broke people's trust in one another. Giovanni Boccaccio, an Italian writer of the time, described it: ""This scourge had implanted so great a terror in the hearts of men and women that brothers abandoned brothers, uncles their nephews, sisters their brothers, and in many cases wives deserted their husbands. But even worse... fathers and mothers refused to nurse and assist their own children"."
