Understanding and tackling snakebite envenoming with transdisciplinary research

Abstract

Snakebite envenoming (SBE) is a neglected tropical disease (NTD) of high global impact. The World Health Organization (WHO) estimates 4.5 to 5.4 million people are bitten by snakes annually, resulting in 1.8 to 2.7 million envenomings, 81,000 to 138,000 deaths, and at least 400,000 people suffering from physical or psychological sequelae [1,2]. SBE mostly affects impoverished rural populations in sub-Saharan Africa, Asia, Latin America, and parts of Oceania, thus fueling a vicious cycle of poverty and illness. SBE not only affects humans, but also domestic animals, including livestock, with negative social and economic consequences [3,4]. This requires a better understanding of the complex social, cultural, and ecological contexts where SBE occurs [5], within the conceptual frame of One Health, an integrated approach that recognizes the health of humans, animals, and the environment as closely linked and interdependent [6]. Such complexity demands more integrative approaches for better understanding and confronting this disease. SBE has unique features that make its prevention and control challenging. Unlike many infectious diseases, SBE cannot be eradicated, but its incidence and impact can be reduced through effective programs aimed at better prevention and rapid access to treatment. This in turn demands the engagement of communities to improve the cohabitation of humans, domestic animals, and snakes in rural agroecosystems. In 2019, the WHO launched a strategy for the prevention and control of SBE, aimed at halving the deaths and disabilities caused by this NTD by the year 2030. This strategy is based on 4 pillars, i.e., empower and engage communities; ensure safe, effective treatment; strengthen health systems; and increase partnerships, coordination, and resources [2]. Building on previous ideas and publications, this article discusses and advocates for transdisciplinary research on SBE and for promoting dialogue and collaboration between sectors, particularly by engaging communities affected by SBE at all levels of the research process.
