Differential mortality of infectious disease in Italian polities: COVID-19, past plague epidemics, and currently endemic respiratory disease.

Coronavirus disease 2019 (COVID-19) has harshly impacted Italy since its arrival in February 2020. In particular, provinces in Italy's Central and Northern macroregions have dealt with disproportionately greater case prevalence and mortality rates than those in the South. In this paper, we compare the morbidity and mortality dynamics of 16th and 17th century Plague outbreaks with those of the ongoing COVID-19 pandemic across Italian regions. We also include data on infectious respiratory diseases which are presently endemic to Italy in order to analyze the regional differences between epidemic and endemic disease. A Growth Curve Analysis allowed for the estimation of time-related intercepts and slopes across the 16th and 17th centuries. Those statistical parameters were later incorporated as criterion variables in multiple General Linear Models. These statistical examinations determined that the Northern macroregion had a higher intercept than the Southern macroregion. This indicated that provinces located in Northern Italy had historically experienced higher plague mortalities than Southern polities. The analyses also revealed that this geographical differential in morbidity and mortality persists to this day, as the Northern macroregion has experienced a substantially higher COVID-19 mortality than the Southern macroregion. These results are consistent with previously published analyses. The only other stable and significant predictor of epidemic disease mortality was foreign urban potential, a measure of the degree of interconnectedness between 16th and 17th century Italian cities. Foreign urban potential was negatively associated with plague slope and positively associated with plague intercept, COVID-19 mortality, GDP per capita, and immigration per capita. Its substantial contribution in predicting both past and present outcomes provides a temporal continuity not seen in any other measure tested here. Overall, this study provides compelling evidence that temporally stable geographical factors, impacting both historical and current foreign pathogen spread above and beyond other hypothesized predictors, underlie the disproportionate impact COVID-19 has had throughout Central and Northern Italian provinces.

Making Endemic Goiter an American Disease, 1800-1820.

In 1800, American physician and naturalist Benjamin Smith Barton (1766-1815) published A Memoir Concerning the Disease of Goitre as it Prevails in Different Parts of North-America. The text documented the nature of the disease in the United States and highlighted how it differed from the ailment's presentation in European patients. While medical topographies were common during this period, Barton's goiter research and the steady stream of American goiter research that followed are worth special attention. This body of literature demonstrates how American physicians understood their relationship to transnational medical discussions and the unique perspective they brought to them. Goiter literature was common in European medical and travel writing during this period and intensely focused on the appearance of the disease in the mountains of Switzerland and Northern Italy. American goiter by its very appearance in non-mountainous regions of the United States contradicted nearly all of the received wisdom about the ailment's cause and potential cure. For two decades, American writers leveraged their own observations and local knowledge to challenge larger narratives in their field.

Escenas en la vida de Srinavasa Ramanujan: Endemias, epidemias y pandemias desde una mirada biomédica y crítica / Scenes of Srinavasa Ramanujan’s life: endemics, epidemics and pandemics from a biomedic and a critic point of view

El hombre que conocía el infinito / The man who knew infinity (2015) de Matt Brown, conjuga problemáticas de las que se ocupa este artículo. El filme se centra en la experiencia del matemático indio Srinavasa Ramanujan en Cambridge, donde sufre situaciones de racismo, discriminación, vivienda precaria, malnutrición. Aun así, logra que reconozcan su genio, siendo nombrado Miembro de la Royal Society of London. Durante su estadía, se desencadena la Primera Guerra Mundial y él enferma de tuberculosis. Sobre este contexto, el trabajo apunta a explorar afecciones que atañen a la humanidad toda: endemias, pandemias, guerra, discriminación. Se trata, de algún modo, de fenómenos, que afectan con intensidad a la salud y bienestar de poblaciones enteras. En ese marco, la visión crítica desde las humanidades permite preguntarse, si bien son eventos que afectan a toda una población, en qué sentido lo hacen diferencialmente respecto a ciertos sectores. Así, se considera el hecho de que hay cuerpos más expuestos, con mayor vulnerabilidad y menores condiciones para afrontar sus efectos. La producción de conocimiento científico no es ajena a esta distribución de la precariedad, como muestra el filme, y es preciso hacer foco en enfermedades desatendidas y de la precariedad en pos de generar condiciones sanitarias más igualitarias. (AU)

The selected film, The man who knew infinity (2015), by Matt Brown, addresses issues which are fundamental to this article’s objectives. The film is about Srinivasa Ramanujan’s experience as an Indian mathematician at Trinity College (Cambridge) where he suffers racism, discrimination, poor housing conditions, malnutrition. Even so, he achieves recognition as a genius, and ultimately becomes an academic member of the College. During his stage in Cambridge, World War I begins, and he gets ill with tuberculosis. In this context, this article aims to explore affections that involve humanity as a whole, such as endemics, pandemics, war, discrimination, among others. It phocuses on phenomena that affect intensely entire populations’ health and wellbeing. In this sense, a critical vision given by the humanities can question the senses in which these three notions affect a whole population, and yet affect it in different ways and intensities. Thus, this work underlines the fact that some bodies are more vulnerable, more exposed to precarization, and have less conditions to overcome its effects. Scientific production of knowledge is not an exception to this distribution of precariousness, as the film shows. In this light, it is necessary to refocus on neglected diseases and precariousness diseases, in order to create egalitarian conditions for prevention and medical treatment. (AU)

[Stigmas, studies, and strife: a history of Brazilian pemphigus, nineteenth and twentieth centuries]. / Estigmas, pesquisas e embates: uma história do pênfigo brasileiro, séculos XIX e XX.

This paper presents a historical narrative about the incidence of pemphigus foliaceus in Brazil in the nineteenth and twentieth centuries. This autoimmune blistering skin disease is more common in children, adolescents, and young adults who live in rural areas of endemic regions. It was first described in Brazil in 1903 by the physician Caramuru Paes Leme. The main foci of the disease are in the Federal District and the states of Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, and São Paulo. This research topic, which has attracted widespread attention from medical practice, especially dermatology, has not received similar attention from historians of health and disease.

Prevention of re-establishment of malaria: historical perspective and future prospects.

Prevention of re-establishment (POR) refers to the prevention of malaria outbreak/epidemic occurrence or preventing re-establishment of indigenous malaria in a malaria-free country. Understanding the effectiveness of the various strategies used for POR is, therefore, of vital importance to countries certified as "malaria-free" or to the countries to be thus certified in the near future. This review is based on extensive review of literature on both the POR strategies and elimination schemes of countries, (i) that have reached malaria-free status (e.g. Armenia, Mauritius, Sri Lanka), (ii) those that are reaching pre-elimination stage (e.g. South Korea), and (iii) countries at the control phase (e.g. India). History has clearly shown that poorly implemented POR programmes can result in deadly consequences (e.g. Sri Lanka); conversely, there are examples of robust POR programmes that have sustained malaria free status that can serve as examples to countries working toward elimination. Countries awaiting malaria elimination status should pre-plan their POR strategies. Malaria-free countries face the risk of resurgence mostly due to imported malaria cases; thus, a robust passenger screening programme and cross border collaborations are crucial in a POR setting. In addition, sustained vigilance, and continued funding for the national anti-malarial campaign programme and for related research is of vital importance for POR. With distinct intrinsic potential for malaria in each country, tailor-made POR programmes are built through continuous and robust epidemiological and entomological surveillance, particularly in countries such as Sri Lanka with increased receptivity and vulnerability for malaria transmission. In summary, across all five countries under scrutiny, common strengths of the POR programmes are (i) a multipronged approach, (ii) strong passive, active, and activated passive case detection, (iii) Indoor residual spraying (IRS), and (iv) health education/awareness programmes.

Tuberculosis in medieval Iceland: evidence from Hofstaðir, Keldudalur and Skeljastaðir.

As part of a larger research project, 274 skeletons from three medieval Icelandic sites were evaluated for signs of infectious disease and 32 were found to have lesions at least consistent with a diagnosis of tuberculosis (TB): eight non-adults ranging in age from infancy to up to 17 years of age, and 24 adults. A higher proportion of individuals from Skeljastaðir and Keldudalur were affected than at Hofstaðir, an observation which may be compatible with Hofstaðir's higher status. A higher number of male skeletons overall (n. 17) than female skeletons (n. 8) exhibited pathological change. The sample is unique for its high numbers of well-preserved infants, and the appearance of TB in children is indicative of continual transmission in a community. The changes recorded in infant remains are marked by destruction and minimal periosteal new bone formation, while one adult skeleton exhibits the classic sign of Pott's disease. Other signs on the skeletons include evidence for past lymphadenitis and iliopsoas (cold) abscess. These cases indicate that TB was likely introduced to Iceland soon after the settlement period and became endemic in different regions from at least the late 10th - mid 13th centuries.

Dr. R. K. Gadgil - An eminent Indian pathologist, pioneer in starting rural medical camps and a researcher who discovered an endemic focus of schistosomiasis in Maharashtra, India.

Dr. Ramchandra Krishnaji Gadgil (RKG) was a pioneer and an eminent researcher. Along with clinician colleagues, he started rural medical camps in 1952, in Maharashtra, India. Through his meticulous research, he discovered in the same year an endemic focus of schistosomiasis in the village, Gimvi, and in 1956, went on to establish a life cycle of the Schistosoma hematobium, involving a completely new intermediate Mollusk host "Ferrisia tenuis", a rather epoch making discovery in the realm of Mollusk intermediate host in relation to human schistosomiasis. His instructions and guidance to the Government Public Health department led eventually to eradication of the schistosomiasis focus in that village in 1969, thereby setting an example for pathologists to head out into the field, do clinical work and pursue with disciplined curiosity a new pathological finding in the laboratory. The fascinating story of his life, education and research is described in this paper.

80th Anniversary of the Publication of Endemic Syphilis in Bosnia: Survey by the School of Public Health in Zagreb.

Certain regions of Bosnia and Herzegovina were prominent European sites of endemic syphilis. In 1934 and 1935 the School of Public Health in Zagreb, later the Andrija Stampar School of Public Health, conducted two surveys on endemic syphilis in Bosnia and Herzegovina. The surveys were well-described in the monograph published in 1939 by the School, under the title Endemic Syphilis in Bosnia: Survey by the School of Public Health in Zagreb ("Endemski sifilis u Bosni anketa Skole narodnog zdravlja u Zagrebu"). This paper provides a description of the publication for the first time, presents the most important data from it, and explores its significance from the historical perspective.

Chagas disease: Historic perspective.

This review is a perspective on the history of Chagas disease, and it adopts a novel approach from literary studies, historical documents and the science and epidemiology of the nature of the disease. From this analysis, comes the review's working definition of the Contact Zone (CZ): "the space in which geographically and historically separated people come into contact with each other and establish long-lasting relationships, which usually involve coercive conditions, radical inequality and intolerable conflict." In the Patient-Physician CZ, we verified the triple transition phenomena: the American trypanosomiasis shifted from a rural, acute, and vectorial transmitted disease to an urban, chronic and non-vectorial disease. In the Academic CZ, we describe the original disagreements which denied the existence of the disease and the current controversies about pathogenic mechanisms and etiological treatment. From the News from Latin America, and in the Original CZ, we will review the evolution of different forms of transmission. As in any good story, research across broad disciplines is necessary to reveal historical perspectives, scientific approaches, and the epidemiology of the disease, which has a prequel of 9000 years and an open ending: thus, we explore across the Global CZ, with its multiple and unexpected actors.

Pierre Richet (1904-1983), fighting onchocerciasis and totalitarism.

While Eugène Jamot's name is associated with the combat against sleeping sickness, Pierre Richet is permanently linked to the battle against river blindness, which he first reported in 1936 in two neighboring households in Garango (Burkina Faso). Onchocerciasis remained a continuous interest, through his last article "The OCCGE and Onchocerciasis", written in 1983. Nonetheless over the course of these five decades, Richet's trajectory was far from that of a specialist dedicating his life to a single disease. After a decade essentially spent fighting trypanosomiasis, came a decade of war in which the specialist in endemism joined the Free French Army and put his organizational know-how at General Lerclerc's disposal, from Morocco to Indochina, via Germany. On his return to Africa in 1953, he extended the principle of mobile teams to the other major endemic diseases accessible to treatment and to vaccines. Richet organized first the combat against leprosy and launched vaccination programs. In 1955, he returned to the battle against onchocerciasis and deployed the first large-scale insecticide program in Chad. The intermediate term failure of this prototype fermented his scientific, interdisciplinary, and organizational thought, which flourished at Bobo-Dioulasso. At the dawn of the independence of French-speaking African countries, and against the political tides of the time, he obtained in 1960 the creation of a supranational organization, the OCCGE, common to 8 countries of West Africa, and he headed it for a decade. Drawing lessons from the past and in the absence of effective pharmaceutical treatment, Richet the physician played the entomological card with one hand, with technical support from Orstom (IRD); this detailed work enabled the development of a strategy. With the other hand, he played the multilateral card, which led in 1974 to the launching of the extraordinary Onchocerciasis Control Program (OCP). If it is Jamot who awakened Africa, Richet is the person who restored its view but also millions of hectares of cultivable land.

[Epidemic and endemic mortality according to causes and sanitary conditions in mid-nineteenth century Lima, Peru]. / Mortalidad por epidemias y endemia según causas y condiciones sanitarias a mediados del siglo XIX en Lima, Perú.

In mid-19th century Lima, Peru, death had various causes. Nonetheless, epidemics raised greater concern among the population and authorities. The highest number of deaths was due to endemic diseases caused by poor sanitary conditions. However, as these were accepted as routine deaths, they were ignored.

A mediados del siglo XIX en Lima, Perú, las personas morían por diversas causas. Pero eran las epidemias las que generaban consternación y preocupación en la población y en las autoridades. Sin embargo, el número mayor de muertes fue por endemias debido a las pésimas condiciones sanitarias de la ciudad. Pero como estas eran muertes cotidianas pasaron desapercibidas.

Yodoprofilaxis, 65 años después suenan las voces del pasado / Iodine prophylaxis, voices from the past after 65 years

En el año 1953, el Dr. Felipe Rodríguez Moreno se incorpora para continuar el trabajo sobre endemia bociosa de la escuela de Granada, liderada por el Dr. Ortiz de Landázuri. En ese paisaje descubre una alta prevalencia de bocio (62% en mujeres), que se relacionaba con el tipo de dieta consumida, de tal forma que los más desfavorecidos tenían una prevalencia de bocio aún mayor. Así mismo, se encuentra una relación familiar en cuanto al bocio, de manera que los sujetos con bocio normalmente tienen un familiar en primer grado también afectado. El agua de bebida es pobre en yodo de forma generalizada, por lo que no hay diferencias significativas en la prevalencia de bocio según la fuente de la que se surtan los paisanos. Solo se encontraron dos mujeres con cretinismo y dos varones afectados de «idiocia». Por ello, cabe pensar que se trata de bocios normofuncionantes. Tras iniciar yodoprofilaxis con sal yodada en Güejar Sierra, se produce un descenso de la prevalencia de bocio de un 53% a un 13% entre los años 1953-1958 (AU)

In 1953, Dr. Felipe Rodríguez Moreno joined the Granada Research Group on Endemic Goiter, which was led by Dr. Ortiz de Landázuri. A high goiter prevalence (62% in women) was found out within the area, and that prevalence was observed to be related to the dietary habits of the time, being the most disadvantaged those who were showing a greater prevalence. A relationship between the high goiter prevalence and the family of the subjects with goiter was also found out, as they usually had a first-degree relative with affection. Iodine content of drinking water was poor throughout the area, so the prevalence was not significantly different between individuals who drank from different water sources. There were only two females with cretinism and two males affected by «idiocy», so the goiters were probably euthyroid. After introducing iodine prophylaxis with iodized salt in Güejar-Sierra, prevalence decreased from 53% to 13% between 1953 and 1958 (AU)

2,000 Year old ß-thalassemia case in Sardinia suggests malaria was endemic by the Roman period.

OBJECTIVES: The island of Sardinia has one of the highest incidence rates of ß-thalassemia in Europe due to its long history of endemic malaria, which, according to historical records, was introduced around 2,600 years ago by the Punics and only became endemic around the Middle Ages. In particular, the cod39 mutation is responsible for more than 95% of all ß-thalassemia cases observed on the island. Debates surround the origin of the mutation. Some argue that its presence in the Western Mediterranean reflects the migration of people away from Sardinia, others that it reflects the colonization of the island by the Punics who might have carried the disease allele. The aim of this study was to investigate ß-globin mutations, including cod39, using ancient DNA (aDNA) analysis, to better understand the history and origin of ß-thalassemia and malaria in Sardinia. MATERIALS AND METHODS: PCR analysis followed by sequencing were used to investigate the presence of ß-thalassemia mutations in 19 individuals from three different Roman and Punic necropolises in Sardinia. RESULTS: The cod39 mutation was identified in one male individual buried in a necropolis from the Punic/Roman period. Further analyses have shown that his mitochondrial DNA (mtDNA) and Y-chromosome haplogroups were U5a and I2a1a1, respectively, indicating the individual was probably of Sardinian origin. CONCLUSIONS: This is the earliest documented case of ß-thalassemia in Sardinia to date. The presence of such a pathogenic mutation and its persistence until present day indicates that malaria was likely endemic on the island by the Roman period, earlier than the historical sources suggest.

Lepra: doença, isolamento e segregação no contexto colonial em Moçambique / Leprosy: disease, isolation, and segregation in colonial Mozambique

Resumo A partir de documentação produzida entre a primeira metade do século XIX e a primeira metade do século XX, prioritariamente relatórios médicos, o artigo aponta as concepções vigentes na comunidade médica colonial e entre as populações locais sobre a lepra, suas manifestações e seu enfrentamento. Enfoca as tensões quanto à prática de segregação dos leprosos e suas implicações sanitárias e sociais. Para compreender as raízes dos discursos e estratégias no meio médico português e colonial, recupera-se a trajetória das definições de isolamento, segregação, lepra e suas aplicações, ou ausência de referência, na literatura de missionários, cronistas e médicos em Angola e Moçambique a partir da segunda metade do século XVII.

Abstract Drawing on documents produced between the early nineteenth and mid-twentieth centuries, mainly medical reports, this paper indicates the prevailing conceptions in the colonial medical community and local populations about leprosy, its manifestations, and how to deal with it. It focuses on the tensions concerning the practice of segregating lepers and its social and sanitation implications. To comprehend the roots of the discourses and strategies in the Portuguese and colonial medical environment, the trajectory of the definitions of isolation, segregation, and leprosy are traced, as are their use in or absence from the writings of missionaries, chroniclers, and doctors in Angola and Mozambique as of the second half of the seventeenth century.

[Rural endemic diseases, health and development: Emmanuel Dias and the construction of a network of allies against Chagas disease]. / Endemias rurais, saúde e desenvolvimento: Emmanuel Dias e a construção de uma rede de aliados contra a doença de Chagas.

The scope of this article is to analyze the trajectory of Emmanuel Dias (1908-1962), a researcher at the Oswaldo Cruz Institute (OCI) and director of the Center for Studies and Prophylaxis of Chagas Disease (OCI outpost established in 1943 in the city of Bambuí, Minas Gerais), as a key actor in the acknowledgement of Chagas disease as a public health problem in Brazil and the Americas. It seeks to show that the conquest of this acknowledgement, the cornerstone of which was the staging of the first campaign to combat the disease in Brazil in 1950, was made possible by the intense political mobilization of Dias together with the various social groups, such as physicians, politicians and residents of rural areas, public health officials, governments and international organizations. This mobilization occurred during the 1940s and 1950s in a historical context marked by intense debate about the relationship between health and development and helped to construct a network of alliances that was critical for the recognition of Chagas disease as a chronic cardiopathy, which threatened the productivity of rural workers and represented a medical and social problem that merited public health actions and programs geared to get it under control.
