Assessing complexity and dynamics in epidemics: geographical barriers and facilitators of foot-and-mouth disease dissemination

Introduction

Physical and non-physical processes that occur in nature may influence biological processes, such as dissemination of infectious diseases. However, such processes may be hard to detect when they are complex systems. Because complexity is a dynamic and non-linear interaction among numerous elements and structural levels in which specific effects are not necessarily linked to any one specific element, cause-effect connections are rarely or poorly observed.

Methods

To test this hypothesis, the complex and dynamic properties of geo-biological data were explored with high-resolution epidemiological data collected in the 2001 Uruguayan foot-and-mouth disease (FMD) epizootic that mainly affected cattle. County-level data on cases, farm density, road density, river density, and the ratio of road (or river) length/county perimeter were analyzed with an open-ended procedure that identified geographical clustering in the first 11 epidemic weeks. Two questions were asked: (i) do geo-referenced epidemiologic data display complex properties? and (ii) can such properties facilitate or prevent disease dissemination?

Results

Emergent patterns were detected when complex data structures were analyzed, which were not observed when variables were assessed individually. Complex properties-including data circularity-were demonstrated. The emergent patterns helped identify 11 counties as 'disseminators' or 'facilitators' (F) and 264 counties as 'barriers' (B) of epidemic spread. In the early epidemic phase, F and B counties differed in terms of road density and FMD case density. Focusing on non-biological, geographical data, a second analysis indicated that complex relationships may identify B-like counties even before epidemics occur.

Discussion

Geographical barriers and/or promoters of disease dispersal may precede the introduction of emerging pathogens. If corroborated, the analysis of geo-referenced complexity may support anticipatory epidemiological policies.

The "Corona Warriors"? Community health workers in the governance of India's COVID-19 response

India's nearly 1-million strong band of quasi-volunteer accredited social health activists (ASHAs) have been key actors in government efforts to control COVID-19. Utilizing a nationalist rhetoric of war, ASHAs were swiftly mobilized by the government in March 2020 as 'COVID warriors' engaged in tracking illness, disseminating information, and caring for quarantined individuals. The speed at which ASHAs were mobilized into mentally and physically grueling labor was all the more stunning given these minimally paid community health workers have long been seen to have low morale given their precarious, informalized work arrangements. Building on work examining the spatialities of global health governance alongside literature on geographic contingency, this paper explores the ways that nationalist COVID-19 war rhetoric promulgated from Delhi worked as a technology of health governance to propel ASHAs into certain forms of action, yet also opened up spaces of potentiality for them to reimagine their relationship to both the state and the communities they serve. In particular, in our analysis of in-depth telephone interviews with ASHA workers in the state of Himachal Pradesh, we find that their hailing as COVID warriors inspired patriotic calls to duty and legitimized their (long over-looked) roles as critical governance actors, yet also was subject to resistance and reworking due to a combination of institutional histories, local politics, as well as happenstantial everyday encounters of ASHA work. The precarious employment of ASHAs - in terms of basic remuneration as well as the great on-the-job risks that they have faced - underscores both the fragile nature of India's health governance system as well as possible political movements for its renewal. We conclude by calling for geographers to give greater attention to community health care workers as a key window into understanding the uneven ways in which health systems are made manifest on the ground, and their ability to respond to citizens' healthcare needs - both in the COVID-19 pandemic and beyond.

Humanitarian inversions: COVID-19 as crisis

COVID-19 is a multi-spectral crisis that has added an acute layer over a panoply of complex emergencies across the world. In the process, it has not only exposed actually-existing emergencies, but also exacerbated them as the global gaze has turned inward. As a crisis, COVID-19 straddles and challenges the boundaries between humanitarianism, development and global health - the frames and categories through which emergencies are so often understood and intervened upon. Reflection on these fundamental categories is, we argue, an important geographical endeavour. Drawing on Geoffrey Bowker's analytical lens of the 'infrastructural inversion', we explore how humanitarianism has been upended by Covid-19 along two axes that are of core concern to geographers: (1) the spatial; and (2) the temporal. We first contextualise current debates on the humanitarian endeavour and its future within recent geographical research. We then set out the complex structure by which COVID-19 has been both imagined and intervened upon as a humanitarian emergency. In so doing, we then pave the way for a deeper empirical analysis of the spatial and temporal inversions that have been brought forth by COVID-19. The paper concludes by examining the conceptual value of the 'inversion' in developing geographical research agendas better attuned to the increasing porosity of humanitarianism, development and global health.

Geographies of uncertainty

The question of uncertainty has generated substantial critical engagements across the social sciences. While much of this literature falls within the domains of anthropology, science studies, and sociology, this short introductory paper highlights how geographical scholarship can also enrich emerging transdisciplinary debates on uncertainty. Specifically, we discuss how geographers engage with uncertainties produced through and reconfigured by some of the most formidable issues of our contemporary moment, including neoliberal transformation, disease and illness, resource conflict, global climate change, and ongoing struggles around knowledge, power, and justice. In conversation with debates in cognate fields, this special issue brings together contributions that grapple with uncertainty through key geographic concepts such as scale, power, spatiality, place, and human-environment relations. This work extends scholarly understanding of how uncertainty arises, is stabilized, and also how people navigate, experience, challenge, and rationalize uncertainty in everyday life. In doing so, we signal the immense potential offered by emerging intersections between human geography and broader critical social science interventions on the question of uncertainty.

"Undisciplined" drinking, multi-sectoralism and political power: Examining problematisations in the Botswana alcohol policy

The Botswana government has recently ramped up efforts to control alcohol consumption through various measures. These include the alcohol tax levy, reduction in trading hours for bars and other licenced premises and increased penalties for alcohol-related road offenses. Whilst these efforts have recently received considerable attention, the processes of alcohol policy development remain unknown and understudied. In this paper, I examine the alcohol policy processes in Botswana using What's the Problem Represented to be (WPR), a poststructural analytic approach that emphasises problematisations in policies. Drawing on alcohol-associated policy documents, I identify two key problematisations that relate to, (1) an emphasis on an "undisciplined" drinker, and (2) an appeal to an internationally-endorsed multi-sectoralism. I explore these problematisations as political formations and periodise them to the year 2008 when they were canonised. I argue that "undisciplined drinking" and an internationally-endorsed multi-sectoralism neglect the social and cultural contexts of drinking, pathologise drinking and do not consider other forms of knowledge. Unmaking current alcohol policy representations is needed to allow for the 'emergence' of alternative conceptualisations of the alcohol 'problem' in Botswana.

The Crisis of Sickle Cell Disease in Africa from Insights into Primary Prevention in Ghana and Nigeria: Notes from the Field

Sickle cell disease (SCD), an inherited blood disorder, impacts 2% of newborns in Nigeria and Ghana. Despite devastating health consequences, SCD prevention is not a priority in either country. This article describes our U.S. research team's feasibility assessment for adapting CHOICES, a computer-based SCD education program, for use in Ghana and Nigeria. We identified indigenous collaborators by reviewing published research and investigating advocacy organizations online. This led to a fact-finding trip to Africa to discuss SCD prevention with local boards of advisors. Three major recommendations emerged from the group discussions: design a culturally appropriate intervention; enlist community healthcare workers to deliver the CHOICES program; and collaborate with religious and community leaders and elders in public awareness campaigns. Based on extensive advisor input, we will modify the content and delivery of the CHOICES intervention to meet the needs of those impacted by SCD in Ghana and Nigeria.

On the Perils of Universal and Product-Led Thinking Comment on "How Neoliberalism Is Shaping the Supply of Unhealthy Commodities and What This Means for NCD Prevention"

Lencucha and Thow's paper offers an important addition and corrective to the burgeoning body of work in public health on the 'commercial determinants of health' in the context of non-communicable diseases (NCDs). Rather than tracing the origins of incoherence across policy sectors to the nefarious actions of industry, they argue that we need to be better attuned to the neoliberal ideologies that underpin these policies. In this commentary I explore two aspects of their argument that I find to be problematic: First, the suggestion that neoliberalism itself has some kind of deterministic or explanatory capacity across vastly different social, spatial, economic and political contexts. Second, I explore their concept of 'product-based NCD risk,' a perspective that disembodies and detaches risk from the social and structural conditions of their making.

Toilet Talk: Eliminating Open Defecation and Improved Sanitation in Nepal

Globally, 2.4 billion people lack adequate sanitation, and open defecation remains common. In this article, I present the qualitative findings from an evaluation of a water, sanitation, and hygiene intervention in remote, mid-West Nepal. The evaluation, conducted in 2014, involved villagers from eight wards in Kotgaun Village Development Committee. Drawing on the concept of the "toilet tripod," I argue as follows: multi-scalar political will provide an important foundation for construction and sustained use of toilets, proximate social pressures contributed significantly to toilet adoption and efforts to eliminate open defecation, and water insecurity constrained improved sanitation and hygiene.
