Flea-borne typhus, due to Rickettsia typhi and R. felis, is an infection causing fever, headache, rash, and diverse organ manifestations that can result in critical illness or death. This is the second part of a two-part series describing the rise, decline, and resurgence of flea-borne typhus (FBT) in the United States over the last century. These studies illustrate the influence of historical events, social conditions, technology, and public health interventions on the prevalence of a vector-borne disease. Flea-borne typhus was an emerging disease, primarily in the Southern USA and California, from 1910 to 1945. The primary reservoirs in this period were the rats Rattus norvegicus and Ra. rattus and the main vector was the Oriental rat flea (Xenopsylla cheopis). The period 1930 to 1945 saw a dramatic rise in the number of reported cases. This was due to conditions favorable to the proliferation of rodents and their fleas during the Depression and World War II years, including: dilapidated, overcrowded housing; poor environmental sanitation; and the difficulty of importing insecticides and rodenticides during wartime. About 42,000 cases were reported between 1931–1946, and the actual number of cases may have been three-fold higher. The number of annual cases of FBT peaked in 1944 at 5401 cases. American involvement in World War II, in the short term, further perpetuated the epidemic of FBT by the increased production of food crops in the American South and by promoting crowded and unsanitary conditions in the Southern cities. However, ultimately, World War II proved to be a powerful catalyst in the control of FBT by improving standards of living and providing the tools for typhus control, such as synthetic insecticides and novel rodenticides. A vigorous program for the control of FBT was conducted by the US Public Health Service from 1945 to 1952, using insecticides, rodenticides, and environmental sanitation and remediation. Government programs and relative economic prosperity in the South also resulted in slum clearance and improved housing, which reduced rodent harborage. By 1956, the number of cases of FBT in the United States had dropped dramatically to only 98. Federally funded projects for rat control continued until the mid-1980s. Effective antibiotics for FBT, such as the tetracyclines, came into clinical practice in the late 1940s. The first diagnostic test for FBT, the Weil-Felix test, was found to have inadequate sensitivity and specificity and was replaced by complement fixation in the 1940s and the indirect fluorescent antibody test in the 1980s. A second organism causing FBT, R. felis, was discovered in 1990. Flea-borne typhus persists in the United States, primarily in South and Central Texas, the Los Angeles area, and Hawaii. In the former two areas, the opossum (Didelphis virginiana) and cats have replaced rats as the primary reservoirs, with the cat flea (Ctenocephalides felis) now as the most important vector. In Hawaii, 73% of cases occur in Maui County because it has lower rainfall than other areas. Despite great successes against FBT in the post-World War II era, it has proved difficult to eliminate because it is now associated with our companion animals, stray pets, opossums, and the cat flea, an abundant and non-selective vector. In the new millennium, cases of FBT are increasing in Texas and California. In 2018–2019, Los Angeles County experienced a resurgence of FBT, with rats as the reservoir.

American Buddhism during World War II imprisonment refers to the Japanese American Buddhist experience between 1942 and 1945 when persons of Japanese ancestry, commonly known as Nikkei Amerikajin, were imprisoned. A discussion of the Nikkei Buddhist experience includes the experiences of Euro-American convert Buddhists who supported them during the imprisonment period. Immediately after the Imperial Japanese Navy attacked Pearl Harbor on December 7, 1941, the Federal Bureau of Investigation (FBI) arrested and interned Japanese Buddhist priests and other leaders of Japanese communities in the United States. In March 1942, the Western Defense Command designated the three West Coast states (Washington, Oregon, and California) and Arizona as Military Area No. 1, from which all persons of Japanese descent, and alien Germans and Italians, were forcefully removed. Following Executive Order 9066 signed by President Franklin D. Roosevelt, the US government removed approximately 120,000 Japanese Americans from the aforementioned military zone and incarcerated them in relocation centers built throughout the continental United States. During that time, the Nikkei community consisted primarily of the Issei, the first generation of Japanese immigrants, and the Nisei, their American-born children. As Tetsuden Kashima defines, the word “internment” refers to the imprisonment of enemy aliens, such as the Issei Japanese nationals, by the Department of Justice and the US Army, while the term “incarceration” refers to the confinement of the Nikkei, including a great number of the Nisei American citizens, by the War Relocation Authority. The word “imprisonment” designates the entire process consisting of internment and incarceration. The study of American Buddhism during World War II is still in its early stages. Finding records and documents related to this subject from the large collections on Japanese American imprisonment is not an easy task. While the National Archives in Washington, DC, maintains the majority of primary sources dealing with Japanese American relocation and incarceration, other institutions, such as the Japanese American National Museum, the University of California-Los Angeles, and museums built around the sites of internment camps, also preserve records. Some of the primary sources are written in Japanese and are located in Japan, which is another stumbling block for researchers who do not read Japanese. Duncan R. Williams’s forthcoming book, American Sutra: Buddhism and the World War II Japanese American Experience, however, will change the current state of scholarship on Japanese American Buddhism during World War II. The forceful relocation of Japanese American Buddhists served to weaken their long-standing efforts to make their ethno-religious practices accepted by America’s general public. Mass incarceration, however, forced the Japanese American Buddhists to further Americanize their religion, generated a set of new Buddhist practices, and gave them opportunities to reflect on their national identities. Buddhist faith and cultural practices associated with Japanese Buddhism contributed to ethnic solidarity, even though the Japanese American community was divided over the issue of US patriotism. During the postwar period, Japanese American Buddhists initiated a campaign to improve their image in the United States and to honor the Nisei Buddhist soldiers who fought during World War II. The formation of American Buddhism was closely connected to the development of US political ideology.

Chlamydia trachomatis is a highly successful parasite of man which is to say that while some disease conditions produced are severe or fatal the majority are relatively minor. Worldwide in distribution, this organism remains the leading cause of blindness, due to trachoma; fully 15% of the world's population may be infected, prompting Sir Macfarlane Burnet to term trachoma one of the three most serious diseases of mankind.1 With the dwindling after World War II of the trachoma problem in the border states (Mason-Dixon line) of the United States, seven hospitals of the US Public Health Service devoted to this disease were closed and interest in chlamydial infections, save for an occasional outbreak of psittacosis, shifted to underdeveloped countries where trachoma remained a problem.

This article analyzes the emergence of national public health capacity in the United States. Tracing the transformation of the federal government's role in public health from the 1910s through the emergence of the CDC during World War II, I argue that national public health capacity emerged, to a great extent, out of the attempts of government officials to deal with the problem of tropical disease within the southern United States during periods of mobilization for war.

Abstract Exploring the construction and maintenance of Nationalist Chinese soldiers’ graves overseas, this article sheds light on post-World War II commemorative politics. After having fought for the Allies against Japanese aggression in the China-Burma-India Theater, the Chinese expeditionary troops sporadically received posthumous care from Chinese veterans and diaspora groups. In the Southeast Asia Theater, the Chinese soldiers imprisoned in the Japanese-run camps in Rabaul were denied burial in the Allied war cemetery and recognition as military heroes. Analyzing archival documents from China, Taiwan, Britain, Australia, and the United States, I demonstrate how the afterlife of Chinese servicemen under foreign sovereignties mattered in the making of the modern Chinese state and its international status.

Abstract There was a time when mission studies benefitted from a symbiotic relationship with the social sciences. However, it appears that relationship has stagnated and now is waning. The argument is made here, in the case of cultural anthropology both in Europe and the United States, that a once mutually beneficial though sometimes strained relationship has suffered a parting of the ways in recent decades. First, the article reviews the relationships between missionaries and anthropologists before World War II when it was possible to be a ‘missionary anthropologist’ with a foot in both disciplines. In that period, the conversation went two ways with missionary anthropologists making important contributions to anthropology. Then, the article reviews some aspects of the development of the two disciplines after World War II when increasing professionalism in both disciplines and a postmodern turn in anthropology took the disciplines in different directions. Finally, the article asks whether or not the conversation, and thus the cross-fertilization, can be restarted, especially since the youngest generation of anthropologists has recognized the reality of local Christianities in their fields of study.
