This paper investigates the events and lessons from the 1848–49 cholera epidemic in Hungary. For contemporaries, the ongoing revolution and civil war pushed the devastation of the cholera epidemic into the background, even though the death rate was similar to that of the earlier 1831 infection. The epidemic hit the country in a period when the revolutionary Hungarian state was waging a war of self-defense. This article strives to refute the historiographic view that the movements of the different armies had a considerable influence on the development of the epidemic. Instead, this article argues that the cholera epidemic was a demographic crisis unfolding in the background of war, but for the most part independently of it. It mattered that most people of that time had already directly experienced cholera and that the Hungarian government did not want to cause panic with restrictive measures. In 1848, cholera was not a “mobilizing factor,” but in 1849 it contributed to the demoralization of the hinterland and frequently appeared in the political propaganda of the civil war.

Following the opening of the Suez Canal in 1869, long-distance pilgrimage to Islamic holy sites expanded and quickened, resulting in the spread of cholera among travelers. The necessity of taking circuitous routes to holy cities both inside and outside Iran significantly exacerbated the spread of cholera. Although potential factors such as inadequate public health infrastructure and ineffective quarantine measures contributed to the dissemination of cholera, overall religious mobility in the form of pilgrimage primarily factored behind cholera's spread. Analyzing the influence of religious mobility and rituals sheds light on how pilgrims, as contagions, dealt with the pandemic and the treatment they received from authorities, members of host societies, and individuals within and outside Iran during the cholera pandemics of the1890s and early 1900s.

In recent years, Lebanon has been struggling with a socioeconomic crisis exacerbated by population displacement after the Syrian crisis, which put a significant burden on its healthcare system. An additional challenge has been the response to a cholera outbreak- a deadly waterborne disease transmitted through the fecal-oral route that usually manifests as severe watery diarrhea and can rapidly progress to death. After reports of a cholera outbreak in Syria were disclosed in September 2022, the Northern Governorate of Lebanon too began reporting cases immediately after, and the first case was confirmed on October 6, 2022. The outbreak rapidly spread to other parts of the country. As of December 9, 2022, a total of 5105 suspected cholera cases with 23 associated deaths were reported across Lebanon. An estimated 45% of these cases were of children and adolescents below the age of 15 years. With the start of the vaccination campaign, awareness programs emphasizing adequate sanitation and clean water sources have become an urgent need.

From the mid-nineteenth century, seamen were increasingly identified as vectors of epidemic diseases such as cholera. The rising acceptance of the germ theories of disease and contagion and the transition from sail to steam at this time increased the fear of the rapid spread of contagious diseases through these mobile people. This article examines how the British naval authorities, ship surgeons and the medical and municipal authorities in the Calcutta sailortown sought to improve maritime health and hygiene to prevent the spread of cholera among and by British seamen. Nineteenth century Calcutta is an ideal context for this study on account of its epidemiological notoriety as a disease entrepot and the sea route between Calcutta and British ports was one of the most closely monitored for disease in the Empire. The article argues that a study of cholera among British seamen can generate important insights into the relationship among disease, medicine and colonialism and in doing so shed light into a neglected aspect of the history of nineteenth century cholera, the British anxiety regarding disease dispersion, practice of hygiene and sanitation and British seamen’s health.

Cholera is one of the major public health problems in the state of Odisha, India since centuries. The current paper is a comprehensive report on epidemiology of cholera in Odisha, which was documented from 1993. PubMed and Web of Knowledge were searched for publications reporting cholera in Odisha during the period 1993–2015. The search was performed using the keywords ‘Odisha’ and/or ‘Orissa’ and ‘Cholera’. In addition, manual search was undertaken to find out relevant papers. During the study period, a total of 37 cholera outbreaks were reported with an average of >1.5 cholera outbreaks per year and case fatality ratio was 0.3%. Vibrio cholerae O1 Ogawa serotype was the major causative agent in most of the cholera cases. The recent studies demonstrated the prevalence of V. cholerae O1, El Tor variants carrying ctxB1, ctxB7 and Haitian variant tcpA allele associated with polymyxin B sensitivity and these variants are replacing the proto type El Tor. The first report of variant ctxB7 in Odisha during super-cyclone 1999 predicted its emergence and subsequent spread causing cholera outbreaks. The prevalence of multidrug-resistant V. cholerae at different time periods created alarming situation. The efficacy trial of oral cholera vaccine (OCV, Shanchol) in a public health set-up in Odisha has shown encouraging results which should be deployed for community level vaccination among the vulnerable population. This paper has taken an effort to disseminate the valuable information of epidemiology of cholera that will influence the policy-makers and epidemiologists for constant surveillance in other parts of Odisha, India and around the globe.

This paper investigates global dynamics of an infection age-space structured cholera model. The model describes the vibrio cholerae transmission in human population, where infection-age structure of vibrio cholerae and infectious individuals are incorporated to measure the infectivity during the different stage of disease transmission. The model is described by reaction–diffusion models involving the spatial dispersal of vibrios and the mobility of human populations in the same domain Ω ⊂ ℝn. We first give the well-posedness of the model by converting the model to a reaction–diffusion model and two Volterra integral equations and obtain two constant equilibria. Our result suggest that the basic reproduction number determines the dichotomy of disease persistence and extinction, which is achieved by studying the local stability of equilibria, disease persistence and global attractivity of equilibria.

This article revisits the origins of internationalism in the field of health and shows how the cholera epidemics of the nineteenth century, much like the current coronavirus crisis, brought global differences such as social inequalities, political hierarchies, and scientific conflicts to the fore. Beyond drawing parallels between the cholera epidemics and the current crisis, the article argues for combining imperial and social histories in order to write richer and more grounded histories of internationalism. It explores this historiographical and methodological challenge by analysing the boardrooms of the international sanitary conferences, Middle Eastern quarantine stations catering for Mecca pilgrims, and ocean steamships aiming to move without delay during a worldwide health crisis.

Recognizing that serious pandemics call forth explanations which go to the heart of beliefs about why natural disasters occur, this article examines three pandemics over the last 200 years (cholera from 1817, Spanish influenza in 1918–19, and COVID-19) to establish whether such explanations have changed significantly over time and, if so, why. What it finds is that this period saw a watershed in which the dominance of traditional religious explanations declined in many parts of the world in the face of the ascent of explanations based on biomedical science. Tracking this momentous change across several faiths and regions globally makes it possible to put into telling historical perspective the stances taken by faith-based communities in response to the current COVID-19 pandemic.

We conducted a matched case-control (MCC), test-negative case-control (TNCC) and case-cohort study in 2016 in Lusaka, Zambia, following a mass vaccination campaign. Confirmed cholera cases served as cases in all three study designs. In the TNCC, control-subjects were cases with negative cholera culture and polymerase chain reaction results. Matched controls by age and sex were selected among neighbours of the confirmed cases in the MCC study. For the case-cohort study, we recruited a cohort of randomly selected individuals living in areas considered at-risk of cholera. We recruited 211 suspected cases (66 confirmed cholera cases and 145 non-cholera diarrhoea cases), 1055 matched controls and a cohort of 921. Adjusted vaccine effectiveness of one dose of oral cholera vaccine (OCV) was 88.9% (95% confidence interval (CI) 42.7–97.8) in the MCC study, 80.2% (95% CI: 16.9–95.3) in the TNCC design and 89.4% (95% CI: 64.6–96.9) in the case-cohort study. Three study designs confirmed the short-term effectiveness of single dose OCV. Major healthcare-seeking behaviour bias did not appear to affect our estimates. Most of the protection among vaccinated individuals could be attributed to the direct effect of the vaccine.

While the cholera outbreak in Haiti still claims victims every month, it is also the backdrop of one of the biggest legal battles the UN has been engaged in – one for the recognition of harm caused and for reparations for victims of cholera. Having used its immunity to disengage from the issue, the UN finally changed its stance in December 2016 and apologized for the organization’s role in the cholera outbreak. This article analyses the role of the elected members of the Security Council – alongside other key stakeholders – in contributing to the UN’s change of policy. Based on privileged access to a number of actors in this politico-legal fight, this article argues that elected members of the Security Council have played a crucial role in pushing the UN to ‘do the right thing’. This article, along with other contributions to this special issue, sheds a different light on the practices inside the Security Council, demonstrating that elected members are far from being powerless, as most of the literature on the subject tends to assume. They can successfully play a significant role inside the organization when the right conditions permit them to play this role.

The cholera and plague pandemics of the 19th and early 20h centuries shaped Ottoman state-building and expansionist efforts in Iraq and the Gulf in significant ways. For Ottoman officials, these pandemics brought attention to the possible role of Qajar and British subjects in spreading cholera and plague, as well as the relationship between Iraq's ecology and recurring outbreaks. These developments paved the way for the expansion of Ottoman health institutions, such as quarantines, and the emergence of new conceptions of public health in the region. Specifically, quarantines proved instrumental not only to the delineation of the Ottoman–Qajar border, but also to defining an emerging Ottoman role in shaping Gulf affairs. Moreover, the Ottomans’ use of quarantines and simultaneous efforts to develop sanitary policies informed by local ecological realities signal a localized and ad hoc approach to disease prevention that has been overlooked. Ultimately, this study demonstrates that environmental factors operating on global and regional scales were just as important as geopolitical factors in shaping Ottoman rule in Iraq and the Gulf during the late Ottoman period.
