Invisible Conquest

Abstract

At the turn of the 20th century, the United States was at war with two seemingly different enemies: the first was Spanish colonial rule in Cuba, Puerto Rico, Guam, and the Philippines. The second enemy was the yellow fever virus which wreaked havoc on the physical and economic welfare of the U.S. In this essay, I conduct a rhetorical history about how the discovery of the mosquito vector for yellow fever was memorialized as a triumph of U.S. medicine, and how medical-military topoi are deployed to describe “conquest” over the virus. I argue that the nonhuman mosquito vector enables retroactive discussion of victory over an invisible enemy, creating rhetorical space between the realities of U.S imperialism and medical violence. This rhetorical history has consequences for how medical-military topoi continue to influence ways that the U.S. uses border control in response to pandemics, particularly those with nonhuman vectors or origins.
