History of Medicine Guide to Tropical Disease Motion Pictures and Audiovisuals Introduction The Tropical Disease Motion Picture and Audiovisual Collection is comprised of films, videorecordings, and digital videocasts produced from the 1920s through 2009, with the majority shot prior to the 1960s. All are devoted to health concerns and include material on medicine and public health. Materials range from ideological, documentary, educational, and training films to American war propaganda. The intended audience is diverse and includes military personnel, health professionals, and the general public. The collection will be of particular interest to scholars concerned with the social, economic, and political implications of health disparities in a world where epidemics travel with great rapidity across national and regional borders. Approximately one billion people are affected by one or more tropical diseases. 1 Tropical diseases are those highly infectious diseases, such as schistosomiasis and cholera, that are more prevalent in hot, humid environments where food and water sources are easily contaminated. Many of these tropical diseases can also thrive in more temperate regions under the right combination of environmental conditions. For example, yellow fever and malaria, known for their tropical origins, were a source of grave concern for American governments during the nineteenth and early twentieth centuries prior to the successes of the Sanitary Movement when water supplies, drainage, and sewage systems were radically improved. Today, most tropical diseases are found primarily in rural areas and poor urban districts of low-income countries in sub-Saharan Africa, Asia, and Latin America, where the resources and technical knowledge needed to implement effective public health measures are largely absent. Three themes emerge from the collection. First, the films show that the early study of tropical disease in the United States is tied closely to military efforts to control the threat of epidemics among troops stationed in tropical regions. 2 The focus expands to general public health efforts when troops reintegrate into civilian populations. Second, the collection demonstrates how infectious diseases that are endemic to less-developed countries in the tropics pose a threat to not only their own economies, but to the financial security of more-developed countries because of business or military connections. Finally, these materials show the heavy burden imposed on the health and economic development of low-income countries in the tropics due to extreme poverty, hunger, and disease. 3 Background The close relationship between tropical medicine and public health can be understood within the historical context of American expansionism. As the United States broadened its territories and increased its wealth in its early years as a republic, this expansion had a significant impact on the development of public health. Eighteenth- and nineteenth-century mercantilism provided the impetus for the creation in 1798 of the Marine Hospital Service, forerunner to the Public Health Service. Constant travel made merchant seamen the most likely vector for foreign sources of infectious disease and the most likely to spark an American epidemic. To ensure the growth of the American economy, the government moved to protect the health of its merchant seamen. 4 The national security threat posed by infectious disease of foreign origin contributed significantly to the expansion of public health practices in the United States during the nineteenth century. 5 Cholera and yellow fever were among the greatest public health concerns of the period, and the efforts of the government to prevent the entry of these diseases across U.S borders have been closely associated with the needs of commerce and security. Yellow fever, for example, was virulent in nature, and its presence in the United States was accompanied by a strong belief in its foreign origin. Yellow fever weakened local economies as officials cordoned off their borders; it was capable of rapidly decimating the population and could paralyze a region due to casualties and fear. The belief that infectious epidemics threatened America's national interest melded American immigration and public health policies during the late nineteenth century-leading to policies still in effect today. 6 Tropical disease, national security, and public health became tightly linked in the first decade of the twentieth century. American business expanded into overseas markets on several continents, necessitating the control of trade routes in the Caribbean and Western Pacific. This was also a time of military expansion, and the establishment of military bases overseas provided compelling reasons for the United States to invest in the study of tropical diseases and the health of nations to which it was economically tied. The first two decades of the twentieth century alone found the United States Army engaged in intensive public health campaigns designed to protect its forces from yellow fever in Cuba and from malaria, dysentery, and dengue in the Philippines; and to control malaria and yellow fever during the construction of the Panama Canal. 7 In 1942, the Malaria Control in War Areas (MCWA) agency was established by the Public Health Service to control malaria outbreaks in army training camps located in the southern states. 8 The agency's successes during World War II at home and abroad gained it a permanent place within the Public Health Service. The division was renamed the Center for Disease Control (CDC), and with the United States Army and the Rockefeller Foundation, took on public health challenges throughout the world. 9 The efforts of these institutions to identify, prevent, and treat diseases endemic to the tropics is a central theme of the collection. The Film Collection Titles in the collection produced prior to the start of World War II highlight United States interests and the public health impact of tropical disease on those interests. For example, films like Gorgas Memorial Institute and Scenes in West Africa reflect American efforts to transform the American tropics and sub-tropics into habitable regions, while the film Work of the Public Health Service depicts the agency's efforts to keep its borders free of diseases from abroad. Doctor They Called the Boss (1986), though produced after World War II, merits a mention here as it documents the work of an early pioneer in tropical medicine. Dr. Lloyd Noland enlisted in the Army medical corps to support the building of the Panama Canal and served under Dr. William C. Gorgas, then chief sanitary officer of the Panama Canal Commission (1913-1914). In 1913, Gorgas recommended Noland for a job as chief medical supervisor for the Fairfield Steel Works Company, a subsidiary of the Tennessee Coal & Iron and Rail Road Company (TCI), located in Birmingham, Alabama. Through interviews with patients, staff, TCI village residents and executives, the film tells how the commercial interests of U.S. Steel, which owned TCI, were translated into company-sponsored public health measures designed to curtail rampant absenteeism in the mines and mills from malaria and typhoid infection. The connection between the U.S. Steel Company's desire to transform the depressed economy of the Birmingham district into the Pittsburgh of the South, and the potential barriers to the needs of commerce in the presence of infectious disease, is conveyed through the recollections of the various interviewees in the film. 10 During World War II motion pictures gained widespread use as a medium to increase public awareness of the war and related health issues. The films provide instruction on keeping soldiers healthy behind enemy lines, and protecting the health of civilians employed in war-related work. Footage shot during the war offers insights into the use of propaganda in public health education, illustrated in the film Pacific Enemy Number 2: Malaria . 11 Its message is aimed at American troops fighting in Japan and emphasizes personal and environmental strategies to stave off malaria infection. The Anopheles mosquito, the vector responsible for the transmission of malaria, is profiled throughout the film as an enemy to the United States-second only to Japan. Another work from the collection deals with wartime public health issues at home. Soldier from the Tropics combines a patriotic call with an instructive message, 12 promoting public health as a civic responsibility. This film about malaria takes place in a small fictional southern town. While the primary narrative is on malaria prevention and the soldier's lax attitude in protecting himself, his loved ones, and his community, a subtext is the threat a malaria epidemic could pose to the success of the war and the American way of life. Films from the collection produced after World War II reflect American dominance. These films were shot during the Cold War, on location in the tropics, and highlight a global interest in the health and human rights of poorer countries even as those interests were often American ones as well. 13 They depict poverty-stricken communities with unsafe water, poor sanitation, and little to no access to basic health care. A majority of the films are clearly intended to benefit American servicemen, health professionals, and/or commercial and philanthropic organizations in occupied territories in the tropics. A sampling of the titles produced in the postwar era point to the alliances America formed or hoped to develop during the Cold War. 14 The film Cholera Today was originally shot in India in 1960 and produced by the Public Health Service. It provides a step-by-step illustration of how to treat a cholera patient with advanced symptoms, a graphic demonstration that begins with an initial evaluation and ends with the regulation of fluid replacement. Its contents suggest the film is intended for American health professionals destined for the region who have had little to no experience with cholera. Other films produced during this period focus on tropical diseases endemic to parts of Africa. Two films, both titled Medicine in the Tropics , were shot in 1948 and 1957. They focus on the collaborative efforts of the government of Liberia, the Firestone Rubber Company, and the Liberian Institute of the American Foundation for Tropical Medicine to respond to the public health issues confronting the region. Together these films highlight the medical problems caused by a number of diseases, among them schistosomiasis, malaria, and smallpox, as experienced by Liberian workers on the Firestone Rubber Company plantation. An explicit theme expressed in these films and many of those produced during the Cold War is the relationship between a healthy workforce and the economic health of a nation. They depict the many ways that tropical disease interferes with the economic development of tropical countries beyond the obvious implications of an infirm workforce. The American economy, in turn, is shown as being intrinsically linked to that of the tropics by virtue of the amount of goods coming from those regions. This seems to be the basic premise for the production of Tropical Disease Investigations in Africa , a film in which its narrator emphasizes explicitly that infectious disease endemic to tropics, if left unchecked, "hampers the exportation of the resources needed by the free world." 15 Uses of the Collection The Tropical Disease Motion Picture and Audiovisual Collection is a rich source of historical documents for researchers of diverse disciplines. Historical epidemiologists, for example, will find the collection contains case studies that deal with infectious epidemics resulting from war, conflict, and poverty. Films from this collection highlight early public health surveillance and laboratory techniques, and are good source material to examine the ideological and epistemological underpinnings of past epidemiological practices. Scholars who view public health in the tropics as a global issue also will find the collection of particular interest. Thematically, the films in this collection trace an ideological shift in American politics and public health policies that spans several twentieth-century wars and conflicts that offer some insight into domestic consequences of tropical diseases. For scholars interested in the social, economic, and political implications of health disparities, the collection provides evidence of public attitudes and government concerns that may be lost in written sources. Teachers also will find the films useful in the interpretation of twentieth-century history, western colonialism, and public health and biomedical practices. An overwhelming majority of the works in the collection were produced by federal, state, and local governments, with various private organizations producing the remainder. Private and public institutions often differed in their goals for undertaking public health interventions in the tropics, while sharing a common humanitarian concern for the health of individuals, communities, or regions. Thus, the collection may be of particular interest to film historians whose research deals with the social impact of film. In addition, most of the films are in the public domain and may be freely used. As the films in this collection show, history is more than the written word. Regardless of discipline, scholars will find that the Tropical Disease Motion Picture and Audiovisual Collection provides an array of powerful visual statements about the social and clinical nature of tropical disease, and excellent source material for interpretation into the nature of poverty, propaganda, and political rhetoric during key moments in American history.
