Infectious disorders, such as plague, cholera, small-pox, etc., may be generally tracked throughout their gradations from their original nests. Those nests are in the East, where the heat of the climate acting upon the filth of semi-savage communities engenders pestilence.
The holy places of both Christians and Mahometans are the receptacles for the masses of people of all nations and classes who have arrived from all points of the compass. The greater number of such people are of poor estate, and many have toiled on foot from immense distances, suffering from hunger and fatigue, and bringing with them not only the diseases of their own remote counties, but arriving in that weak state that courts the attack of any epidemic. Thus crowded together, with a scarcity of provisions, a want of water, and no possibility of cleanliness, with clothes that have been unwashed for weeks or months, in a camp of dirty pilgrims, without any attempt at drainage, an accumulation of filth takes place that generates either cholera or typhus; the latter, in its most malignant form, appears as the dreaded “plague.”
