Global health (security), immigration governance and Covid-19 in South(ern) Africa: An evolving research agenda.

The Covid-19 pandemic provides a stark reminder of the political tensions associated with the field of immigration and health, highlighting the central role that nationalism, racism and xenophobia play in determining responses to communicable diseases. The blurring of global health, immigration governance, and the global health security agendas has long been recognised. However, an improved understanding of the politics influencing these entanglements, specifically within the context of the Covid-19 response in low- and middle-income country contexts, is urgently needed. This includes - but is not limited to - the immediate concerns surrounding inclusive social, political and medical responses to Covid-19; vaccine nationalism - at both global and national levels; and calls for 'vaccine passports'. To this end, we draw on the Southern African Development Community (SADC) context - one associated with high levels of diverse population movements and a large burden of communicable diseases - to explore responses to Covid-19. We unpack tensions surrounding the management of migration and the ways in which sovereignty impacts attempts at building regional, coordinated responses to migration and health, and consider how this affects progress towards global health targets. With an initial focus on South Africa, we build on previous work exploring the blurring of global health, immigration governance, and the global health security agendas in SADC, and draw from ongoing research on the governance of migration and health within the region. This includes current and evolving research exploring migration and Covid-19, initiated in March 2020 when the first cases of Covid-19 were identified in Southern Africa. The aim is for these findings to catalyse a new and evolving researh agenda to inform the development and implementation of appropriate pandemic responses in a region associated with some of the highest levels of inequality globally. To this end, an evolving research agenda should be responsive to current needs. We suggest that, in SADC, priority research should focus on improving our understanding of (1) the political factors influencing the (dis)connections between migration and health governance structures in the context of Covid-19, and how to overcome these in the context of a pandemic; and (2) the motivations for and implications of a 'vaccine passport' system on movement within and beyond the SADC region. This requires a reactive, cross-disciplinary, regional research network. In a context where funding for research is increasingly inaccessible, this requires innovative, informal, collaborative engagement.

Research on the move: exploring WhatsApp as a tool for understanding the intersections between migration, mobility, health and gender in South Africa.

BACKGROUND: Reflecting global norms, South Africa is associated with high levels of cross-border and internal population mobility, yet migration-aware health system responses are lacking. Existing literature highlights three methodological challenges limiting the development of evidence-informed responses to migration and health: (1) lack of engagement with the process of migration; (2) exclusion of internal migrants; and (3) lack of methodologies that are able to capture 'real-time' data about health needs and healthcare seeking experiences over both time and place. In this paper, we reflect on a four-month pilot project which explored the use of WhatsApp Messenger - a popular mobile phone application used widely in sub-Saharan Africa - and assessed its feasibility as a research tool with migrant and mobile populations in order to inform a larger study that would address these challenges. METHOD: A four-month pilot was undertaken with eleven participants between October 2019 and January 2020. Using Survey Node, an online platform that allows for the automatic administration of surveys through WhatsApp, monthly surveys were administered. The GPS coordinates of participants were also obtained. Recruited through civil society partners in Gauteng, participants were over the age of 18, comfortable engaging in English, and owned WhatsApp compatible cell phones. Enrolment involved an administered survey and training participants in the study protocol. Participants received reimbursement for their travel costs and monthly cell phone data. RESULTS: Out of a possible eighty eight survey and location responses, sixty one were received. In general, participants responded consistently to the monthly surveys and shared their location when prompted. Survey Node proved an efficient and effective way to administer surveys through WhatsApp. Location sharing via WhatsApp proved cumbersome and led to the development of a secure platform through which participants could share their location. Ethical concerns about data sharing over WhatsApp were addressed. CONCLUSIONS: The success of the pilot indicates that WhatsApp can be used as a tool for data collection with migrant and mobile populations, and has informed the finalisation of the main study. Key lessons learnt included the importance of research design and processes for participant enrolment, and ensuring that the ethical concerns associated with WhatsApp are addressed.

Using WhatsApp messenger for health systems research: a scoping review of available literature.

Globally, the use of mobile phones for improving access to healthcare and conducting health research has gained traction in recent years as rates of ownership increase, particularly in low- and middle-income countries (LMICs). Mobile instant messaging applications, including WhatsApp Messenger, provide new and affordable opportunities for health research across time and place, potentially addressing the challenges of maintaining contact and participation involved in research with migrant and mobile populations, for example. However, little is known about the opportunities and challenges associated with the use of WhatsApp as a tool for health research. To inform our study, we conducted a scoping review of published health research that uses WhatsApp as a data collection tool. A key reason for focusing on WhatsApp is the ability to retain contact with participants when they cross international borders. Five key public health databases were searched for articles containing the words ‘WhatsApp’ and ‘health research’ in their titles and abstracts. We identified 69 articles, 16 of which met our inclusion criteria for review. We extracted data pertaining to the characteristics of the research. Across the 16 studies—11 of which were based in LMICs—WhatsApp was primarily used in one of two ways. In the eight quantitative studies identified, seven used WhatsApp to send hyperlinks to online surveys. With one exception, the eight studies that employed a qualitative (n = 6) or mixed-method (n = 2) design analysed the WhatsApp content generated through a WhatsApp-based programmatic intervention. We found a lack of attention paid to research ethics across the studies, which is concerning given the controversies WhatsApp has faced with regard to data protection in relation to end-to-end encryption. We provide recommendations to address these issues for researchers considering using WhatsApp as a data collection tool over time and place.

Responding to the health needs of migrant farm workers in South Africa: Opportunities and challenges for sustainable community-based responses.

Reflecting global trends, migrant farm workers in South Africa experience challenges in accessing healthcare. On the commercial farms in Musina, a sub-district bordering Zimbabwe, Medécins sans Frontières and the International Organization for Migration both implemented migration-aware community-based programmes that included the training of community-based healthcare workers, to address these challenges. Using qualitative data, this paper explores the experiences that migrant farm workers, specifically those involved in the programmes, had of these interventions. A total of 79 semi-structured interviews were completed with migrant farm workers, farm managers, NGO employees and civil servants between January 2017 and July 2018. These data were supplemented by a review of grey and published literature, as well as observation and field notes. Findings indicate that participants were primarily positive about the interventions. However, since the departure of both Medécins sans Frontières and the International Organization for Migration, community members have struggled to sustain the projects and the structural differences between the two programmes have created tensions. This paper highlights the ways in which local interventions that mobilise community members can improve the access that rural, migrant farming communities have to healthcare. However, it simultaneously points to the ways in which these interventions are unsustainable given the realities of non-state interventions and the fragmented state approach to community-based healthcare workers. The findings presented in this paper support global calls for the inclusion of migration and health in government policy making at all levels. However, findings also capture the limitations of community-based interventions that do not recognise community-based healthcare workers as social actors and fail to take into account their motivations, desires and need for continued supervision. As such, ensuring that the ways in which migration and health are included in policy making are sustainable emerges as a necessary element to be included in global calls.

After the handover: Exploring MSF's role in the provision of health care to migrant farm workers in Musina, South Africa.

Non-state actors, including humanitarian agencies, play a prominent role in providing health care in low- and middle-income countries. Between 2007 and 2009, Musina, a South African municipality bordering Zimbabwe, became the site of several interventions by non-state organisations as an unprecedented number of Zimbabweans crossed the border, putting strain on already burdened local systems. After the initial need for humanitarian relief dissipated, organisations started to implement projects that were more developmental in nature. For example, Médecins sans Frontières developed a mobile clinic programme to improve health care access for migrant farm workers, a programme that was subsequently integrated into the Department of Health. Since the handover of the programme, it has faced multiple challenges. Using qualitative methodology and a case study approach, this paper traces the development of the programme, exploring the changing relationship between MSF and the state during this time. This research raises questions about the implications of short-term 'innovative' interventions targeting the access that migrants have to care, within a context in which policy and programmatic responses to health are not migration aware. Furthermore, it highlights the ways in which the energies and resources of local DoH employees were redirected by MSF's involvement in the area.

Exploring The Migration Profiles of Primary Healthcare Users in South Africa.

South Africa's public healthcare system responses seldom engage with migration. Our exploratory study investigates migration profiles and experiences of primary healthcare (PHC) users. A cross-sectional survey involving non-probability sampling was conducted with 229 PHC users at six purposively selected PHC clinics in three districts of SA. The survey captured socio-demographic information, migration histories, and PHC experiences. Chi square and Fischer's exact tests were used to compare categorical variables, whilst Mann-Whitney U tests compared continuous variables between groups. Most PHC users were migrants (22% internal South African; 45% cross-border) who generally move for reasons other than healthcare seeking. Length of time accessing services at a specific clinic was shown to be key in describing experiences of PHC use. Understanding population movement is central to PHC strengthening in SA and requires improved understanding of mobility dynamics in regard to not just nationality, but also internal mobility and length of stay.
