On repeated occasions in the nineteenth century, Asian cholera irrupted from its traditional center in the great river basins of India and spread in pandemic waves throughout parts of Europe, North Africa, and North America. In Spain alone 600,000 deaths resulted from cholera during four great invasions (Cárdenas, 1971: 224). The United States experienced terrifying outbreaks beginning in 1832, 1849, and 1866 (Rosenberg, 1962) which also touched parts of Mexico, Central America, and the Caribbean. Initially South America escaped the onslaught. Some Brazilians speculated that the intense heat of the equator, or the vast expanse of the Atlantic ocean, somehow offered an effective buffer to the southward spread of cholera (Rego, 1872: 84). But this “sweet illusion” was shattered in 1855. Indeed the first city in Brazil struck by Asian cholera was Belém, capital of the vast northern province of Pará located astride the equator at the mouth of the Amazon river.
