THE COLONY OF A CIVILIZED NATION which takes possession, either of waste country, or of one so thinly inhabited, that the natives easily give place to the new settlers, advances more rapidly to wealth and greatness than any other human society.

—Adam Smith, An Inquiry into the Nature and Causes of the Wealth of Nations (1776)

OLD WORLD GERMS were entities having size, weight, and mass, just like Sweet Betsy, her Ike, and their animals; germs required transportation across the oceans, which the marinheiros unintentionally supplied. Once ashore and lodged in the bodies of new victims in new lands, their rate of reproduction (as often as every twenty minutes) enabled them to outperform all larger immigrants in rapidity of increase and speed of geographical expansion. Pathogens are among the “weediest” of organisms. We must examine the colonial histories of Old World pathogens, because their success provides the most spectacular example of the power of the biogeographical realities that underlay the success of European imperialists overseas. It was their germs, not these imperialists themselves, for all their brutality and callousness, that were chiefly responsible for sweeping aside the indigenes and opening the Neo-Europes to demographic takeover.

Until recently, the chroniclers of human history had no knowledge of germs, and most believed epidemic disease to be supernatural in origin, something to be piously endured but rarely chronicled in detail. Therefore, the epidemiological history of the European colonies beyond the seams of Pangaea is like a jigsaw puzzle of 10,000 pieces, of which we have only half – enough to give us an idea of how large the original was and of its major features, but not enough for a neat reassembly. We bemoan the spottiness of our information; yet so great is its quantity and so neatly does it parallel accounts of the modern experience of what happens to isolated peoples when they are dragooned into the world community that we cannot doubt its general validity. Before we approach the history of Old World pathogens in the Americas and Australasia, let us take a look at a few recent examples of what science calls virgin soil epidemics (rapid spread of pathogens among people whom they have never infected before), in order to accustom ourselves to the possibilities of epidemiological catastrophe. When in 1943 the advance of the Alaska Highway exposed the Amerindians of Teslin Lake to fuller contact with the outside world than they had ever had before, they underwent in one year epidemics of measles, German measles, dysentery, catarrhal jaundice, whooping cough, mumps, tonsillitis, and meningococcal meningitis. When in 1952 the Amerindians and Eskimos of Ungava Bay, in northern Quebec, had an epidemic of measles, 99 percent became sick, and about 7 percent died, even though some had the benefit of modern medicine. In 1954, an epidemic of the same “minor” infection broke out among the people of Brazil’s remote Xingu National Park. The death rate was 9.6 percent among those of the afflicted who had modern medical treatment, and 26.8 percent among those who did not.
