Among the most accessible and fascinating accounts of the 1346 Black Death and the later 1665 plague are D. Defoe,

The trend of blaming the Jews for the Black Death began in what is today called Switzerland and spread quickly throughout Europe. In most cities, the persecutions were started by lower-class tradesmen and peasants who were whipped into frenzies by overzealous monks and priests. In some cities these activities were officially sanctioned by local authorities. In Basel, for example, the town leadership voted to kill all Jews, destroy their homes, and ban Jews from entering the city for another two centuries. On the other hand, there were those in power who opposed such actions and sought to protect Europe's Jewish population. Pope Clement VI gave Jews safe haven inside his papal residence in Avignon. Emperor Charles IV of France tried to stop persecutions in his country, but was overridden by nobles who hoped to avoid paying off debts by letting the mobs kill their Jewish creditors. Duke Albert of Austria was labeled a “Jew-master” because he protected hundreds of Jewish families, allowing them sanctuary inside his fortress. For further details, see J. F. C. Hecker,

Ages, B. G. Babington, trans. (London: Sydenham Society, 1844).

Such a level of microbe-induced mass destruction would not be achieved again until the influenza epidemic of 1918â19. It would be surpassed by AIDS, which over a twenty-year period between 1980 and 2000 is projected to claim an estimated 24 million people, 20 million of whom will have died of the disease by the year 2000. See J. Mann, D. J. M. Tarantola, and T. W. Netter,
AIDS in the World

Earlier circumstantial evidence led Joseph Needham to conclude that China had leprosy prior to A.D. 500, but skeletal studies found no clear leprotic remains in Asia until well after the medieval leprosy epidemic of Europe. See V. Moller-Christensen. “Evidence of Leprosy in Earlier Peoples,” in Brothwell and Sandison, eds. (1967), op. cit. Indeed, the greatest leprosy epidemics of Asia followed European colonialism of the region during the eighteenth century.

In one particularly ingenious mid-twentieth-century study researchers placed caged guinea pigs in the sealed rooms of human tuberculosis patients. The scientists calculated that, provided the patient's room wasn't aired out, the tiny guinea pig lungs inhaled thirty infectious TB particles a day. The far larger human lung would presumably absorb ten to twenty times as many particles daily under the same circumstances. See R. L. Riley, C. C. Mills, F.

Consumption was a particular concern. The numbers of cases rose steadily. In Massachusetts, for example, death certificate reports listed consumption (tuberculosis) as the cause of death for 1,634
individuals in 1844; by 1846 that figure was 2,567. And the consumption death reports jumped to 4,593 in 1853. The state's total population in the 1850 census was 994,665. Between 1849 and 1853, a total of 20,000 peopleâmost of them residents of Bostonâdied of consumption. That was about 2 percent of the population. Far more people were sick with the disease, which, like AIDS 120 years later, killed so slowly that statistics never actually reflected at a given moment the full toll of the disease on society.

Noteworthy for the future would be a largely ignored fact in 1970: namely, that tuberculosis skin tests showed that the highest rates of infection in the United States that year were among poor African-American residents of seven Deep South states, and 85 percent of New York City residents who tested positive in TB skin tests that year were blacks who had recently moved to the city from the Deep South.

For example, between 1937 and 1947 the numbers of South African families on waiting lists for housing in Johannesburg's black- and colored-designated communities rose from 11 to 16,195. During the subsequent decade the apartheid government decreased its commitment to subsidized housing construction for poor and working-class families from a 1949 high of 7,407 houses to 1957's low of 155. During the same time construction of so-called economic housing, built at government expense for white working- and middle-class families, rose from 348 houses in 1947 to 15,364 in 1957.

When the spirochete enters sores on the skin's surface it remains in the vicinity of its initial site of infection. Over time the organism may invade local bone, cartilage, and skin, but infection is rarely systemic. In contrast, sexual transmission of the syphilis spirochete provides immediate access to the blood system, allowing for disease in every organ in the body. The localized yaws infections often resolved without treatment in a matter of weeks, but once syphilis gained entry to the bloodstream most people were fated to suffer systemic illness and, in many cases, slow death.
