الشرح
The pattern of infection followed commerce: the disease appeared first at busy harbours and then worked inland along the roads and rivers that carried goods, which is why coastal cities were struck before inland districts. The idea of returning crusading armies fails because the great expeditions to the east belong to earlier centuries, while this outbreak arrived with merchant shipping.
