Public health, urban space and social exclusion in postwar Spain: the exanthematic typhus epidemic in the city of Valencia, 1941-1943. / Salud pública, espacio urbano y exclusión social en la España de posguerra: la epidemia de tifus exantemático en la ciudad de Valencia, 1941-1943.

After the Spanish Civil War, poor hygiene and nutritional deficiencies among a large part of Spain's population contributed to the rise of epidemic diseases. Exanthematic typhus posed a challenge to the health authorities, especially during the spring of 1941, when the epidemiological cycle of the disease and the lack of infrastructures combined to create a serious health crisis. The Franco regime, aware that this situation posed a threat to its legitimacy, promptly used social exclusion as part of its health policy against the epidemic. This article provides an in-depth analysis of the case of Valencia, a city that was behind Republican lines during the war, and therefore received successive waves of refugees as Franco's troops advanced.

Typhus, yellow fever and Medicine in Mexico during the French intervention / El tifo, la fiebre amarilla y la medicina en México durante la intervención francesa.

French intervention in Mexico (1861-1867) is particularly full of episodes of patriotic heroism in terms of military, politic and, even, religious affairs, however this history is also rich in episodes related to diseases and the evolution of Mexican scientific medicine practice, epidemics such as typhus (nowadays knows as rickettsiosis), yellow fever, or cholera. Principally, this context outlined the Mexican history and influenced the course of the nation. The epidemics served as fertile land for the development of medicine science leading by prominent physicians, particularly by doctor Miguel Francisco Jiménez.

El periodo comprendido entre 1861 y 1867, marcado por la ocupación extranjera, particularmente por Francia, es sin lugar a dudas rico en gestas de patriotismo sin igual en la historia de México por la coyuntura política, militar e incluso religiosa del periodo en cuestión; sin embargo, poco se ha abordado de manera concreta el estado que guardaban la salud y la ciencia médica en dicho periodo, lleno de episodios sumamente interesantes en cuanto a epidemias como el tifo, la fiebre amarilla o el cólera, sobre todo cuando estas enfermedades afectaron y marcaron el rumbo de la historia nacional, a la par con el desarrollo de la naciente medicina científica mexicana encabezada por varios médicos, en especial por el Dr. Miguel Francisco Jiménez.

[Typhus in Mexico City in 1915]. / El tifo en la Ciudad de Mexico en 1915.

The year 1915 was particularly difficult; it was characterized by droughts, famines, and outbreaks of diseases including typhus.This text exposes its spread in Mexico City as well as the measures implemented to combat it, carried out before knowing the etiology of the illness, focused on cleaning up the environment and the measures undertaken afterwards with the aim of delousing people.

In severe health crisis like those of 1854-1856, 1899 and 1918, especially in Porto, where cholera morbus, the bubonic plague, typhus fever, pneumonic influenza and smallpox killed high percentages of the population, the images of the epidemics in the press enable us to identify the scientific knowledge in a country considered peripheral, but which had studies and personnel specialized at the most advanced levels for the time. A database of 6,700 news items and announcements reveals the medical and pharmaceutical knowledge of the second half of the nineteenth and early twentieth centuries, the way it was transmitted and disclosed to the public and the solutions offered by the health authorities. Hygiene was consistently highlighted in the news and announcements.

Em períodos de crise sanitária grave como os de 1854-1856, 1899 e 1918, especialmente no Porto, onde cólera-morbo, peste bubónica, tifo exantemático, gripe pneumónica e varíola mataram percentagens elevadas da população, as imagens das epidemias na imprensa permitem-nos identificar os conhecimentos científicos num país considerado periférico, mas que dispunha de estudos e pessoal especializado no nível dos mais avançados da época. Uma base de dados de 6.700 notícias, artigos e anúncios revela-nos o conhecimento médico e farmacêutico da segunda metade do século XIX e início do XX, o modo como era transmitido e divulgado ao público e as soluções apresentadas pelas autoridades sanitárias. Um fator foi sempre salientado nas notícias e anúncios: a higiene.

Drought and epidemic typhus, central Mexico, 1655-1918.

Epidemic typhus is an infectious disease caused by the bacterium Rickettsia prowazekii and transmitted by body lice (Pediculus humanus corporis). This disease occurs where conditions are crowded and unsanitary. This disease accompanied war, famine, and poverty for centuries. Historical and proxy climate data indicate that drought was a major factor in the development of typhus epidemics in Mexico during 1655-1918. Evidence was found for 22 large typhus epidemics in central Mexico, and tree-ring chronologies were used to reconstruct moisture levels over central Mexico for the past 500 years. Below-average tree growth, reconstructed drought, and low crop yields occurred during 19 of these 22 typhus epidemics. Historical documents describe how drought created large numbers of environmental refugees that fled the famine-stricken countryside for food relief in towns. These refugees often ended up in improvised shelters in which crowding encouraged conditions necessary for spread of typhus.

[Exanthematic typhus epidemic in Chile (1932-1939)]. / Epidemia de tifus exantemático en Chile (1932-1939).

After the great epidemic of the exanthematic typhus of 1918-1919 in Chile, there was a gradual decrease in the number of cases , until it became endemic around 1926. Starting in 1932 and until 1939 a new epidemic outbreak occured that prompted researchers to its study supported by the new clinical and technological advances of this period. Subsequently, two important events occured: the erradication of the vector ( human louse) by means of effective insecticides and the discovery of an effective antibiotic treatment.

100th anniversary of the death of Ricketts: Howard Taylor Ricketts (1871-1910). The namesake of the Rickettsiaceae family.

The US American pathologist and microbiologist Howard Taylor Ricketts died 100 years ago. He is renowned for discovering the causative organism and the transmission route of Rocky Mountain spotted fever and of tabardillo--an epidemic louse-borne typhus occurring especially in Mexico. He also found that both diseases were caused by related infectious agents (Rickettsia rickettsii and Rickettsia prowazekii). The scientific community therefore named both a taxonomic family (Rickettsiaceae) and an order (Rickettsiales) after the scientist. Ricketts' work on immunity and serums became the basis for further advances in vaccine development.

Investigações das riquetsioses: contribuições de cientistas brasileiros / Rickettsiosis investigations: contributions of Brazilian scientists

Justificativa e objetivos: Um crescente interesse em História da Medicina motivou uma investigação de cientistas brasileiros que tenham se destacado em pesquisas médicas. O objetivo do presente estudo foi descrever a história destes cientistas, que muito contribuíram para o conhecimento das riquetsioses. Conteúdo: Durante pesquisa a respeito da descoberta do agente causal do tifo exantemático, doença que por séculos dizimaram viajantes e populações aglomeradas de vilas e cidades europeias encontrou-se o nome de Henrique da Rocha Lima. Este brilhante cientista, além de descobrir o agente causal do tifo, revelou ao mundo um novo gênero de bactérias, as Rickettsias. No Brasil, uma riquetsiose adquiriu relevância epidemiológica a partir da década de 1920: a febre maculosa. Vários brasileiros se destacam em suas pesquisas, dentre eles Amílcar Viana Martins, Octávio de Magalhães e Jose Toledo Piza. Conclusão: Se atualmente há conhecimento e possibilidade de combater as riquetsioses, deve-se a estes pesquisadores, que com muito trabalho e dedicação desvendaram seus aspectos etiológicos, clínicos e fisiopatológicos.

Background and objectives: A special interest in History of Medicine led us to investigate the role of Brazilians who excelled in medical research. In the present study, we describe the contributions of such scientists in nriching the medical knowledge about rickettsiosis. Contents: We have found in the discovery of the causal agent of epidemic exanthematous typhus, a disease that for centuries afflicted travelers and overcrowded European cities and villages, the name of Henrique da Rocha Lima. This brilliant scientist, besides discovering the causal agent of epidemic exanthematous typhus, revealed to the world a new genus of bacteria, the rickettsia. In Brazil, a rickettsial disease acquired epidemiological relevance after the decade of 1920: the Brazilian spotted fever. Several outstanding researchers were involved in this pioneer research, especially Amílcar Viana Martins, Octávio de Magalhães and Jose Toledo Piza. Conclusion: If today we know about rickettsiosis and we can treat them, we owe this fact to these investigators who, with much work and dedication, solved its etiological, clinical and physiopatological aspects.

Los juaninos frente a las epidemias / The juaninos facing epidemics

El presente artículo aborda la participación de la orden de San Juan de Dios durante las diversas epidemias que se dieron durante el periodo novohispano, especialmente en el siglo XVIII con eltemido matlazáhuatl. Como antecedente se mencionan las principales epidemias del siglo XVI y como con la llegada de la Orden hospitalaria en el siglo XVII cambió el sistema de salud novohispano. La orden tuvo un campo de acción extenso conformando una red de casi 40 establecimientos para el territorio novohispano, ya que su expansión incluyó también los otros virreinatos americanos. (AU)

A stranger to our camps: Typhus in American history.

Medical observers during the American Civil War were happily surprised to find that typhus fever rarely made an appearance, and was not a major killer in the prisoner-of-war camps where the crowded, filthy, and malnourished populations appeared to offer an ideal breeding ground for the disease. Through a review of apparent typhus outbreaks in America north of the Mexican border, this article argues that typhus fever rarely if ever extended to the established populations of the United States, even when imported on immigrant ships into densely populated and unsanitary slums. It suggests that something in the American environment was inhospitable to the extensive spread of the disease, most likely an unrecognized difference in the North American louse population compared to that of Europe.
