The leishmaniases are a group of four vector-borne neglected tropical diseases (NTDs) with 1.6 billion people in some 100 countries at risk. They occur in certain eco-epidemiological foci that reflect manipulation by human activities, such as migration, urbanization and deforestation, of which poverty, conflict and climate change are key drivers. Given their synergistic impacts, risk factors and the vulnerabilities of poor populations and the launch of a new 2030 roadmap for NTDs in the context of the global sustainability agenda, it is warranted to update the state of knowledge of the leishmaniases and their effects. Using existing literature, we review socioeconomic and psychosocial impacts of leishmaniasis within a framework of risk factors and vulnerabilities to help inform policy interventions. Studies show that poverty is an overarching primary risk factor. Low-income status fosters inadequate housing, malnutrition and lack of sanitation, which create and exacerbate complexities in access to care and treatment outcomes as well as education and awareness. The co-occurrence of the leishmaniases with malnutrition and HIV infection further complicate diagnosis and treatment, leading to poor diagnostic outcomes and therapeutic response. Even with free treatment, households may suffer catastrophic health expenditure from direct and indirect medical costs, which compounds existing financial strain in low-income communities for households and healthcare systems. The dermatological presentations of the leishmaniases may result in long-term severe disfigurement, leading to stigmatization, reduced quality of life, discrimination and mental health issues. A substantial amount of recent literature points to the vulnerability pathways and burden of leishmaniasis on women, in particular, who disproportionately suffer from these impacts. These emerging foci demonstrate a need for continued international efforts to address key risk factors and population vulnerabilities if leishmaniasis control, and ultimately elimination, is to be achieved by 2030.

The looming threat of climate change urgently calls for reimagining unsustainable systems and practices, including academia’s culture of emissions-intensive travel. Given that medical educators are uniquely invested in the future of the trainees they represent, this reimagination can and should begin with medical education. Making significant reforms to the application process has historically been challenging, but the COVID-19 pandemic catalyzed an abrupt shift from in-person to virtual interviews for medical school, residency, and fellowship. Programs and applicants alike demonstrated resilience, innovation, and satisfaction in adapting to virtual interviews during 2 full application cycles. This restructuring has prompted consideration of the necessity of environmentally costly, expensive, and time-consuming cross-country travel for single-day interviews. However, evolving conversations about the future of medical training interviews have not prioritized environmental impact, despite the sizeable historical emissions generated by interview-related travel and the incompatibility between ecological damage and population health. Beyond environmental impact, virtual interviews are more equitable, with significantly fewer financial costs, and they are more efficient, requiring less time off from school or work. Many concerns associated with virtual interviews, including interview inflation and limited applicant exposure to programs and their surrounding areas, can be addressed via creative and structural solutions, such as interview caps and in-person second-look programs. The medical training interview process underwent a forced restructuring due to the unprecedented disruption caused by COVID-19. This moment presents a strategic inflection point for medical education leadership to build on the momentum and permanently transform the process by focusing on sustainability and equity.
