About snakebite envenoming
Every year, over 5.8 billion people are at risk of encountering a venomous snake, resulting in approximately 5 million bites and up to 2.7 million cases of envenoming: when a venomous snake injects toxins into a human body.
Preventing bites from ever happening is important, but humans and snakes will always coexist and these dangerous incidents will continue to occur. Our focus is to ensure rapid, effective intervention when they do.
What is unique about snakebite?
Snakebite is distinct from other neglected tropical diseases due to its acute and unexpected nature, which requires appropriate and time-critical responses. This challenge is compounded by the extraordinary diversity of venom toxins across species and regions.
While snakebite presents unique clinical challenges, many of the barriers to care are cross-cutting, systemic hurdles in logistics, communication, and infrastructure that are shared across global health.
Investment in this space has historically been low due to scarce and fragmented burden data, a lack of global visibility, and a perception that snakebite is ‘unsolvable’ because it’s not traditionally eliminable. Thus, innovation has stalled across the entire patient journey. Experts have noted challenges at every level, requiring innovation in multiple areas.
Who is most affected by snakebite?
The burden of snakebite is felt most acutely by rural, poor, and agrarian communities predominantly in Sub-Saharan Africa, South Asia, South-East Asia, and Latin America. In many of these high-burden settings, people work outdoors and live far from health facilities, making them vulnerable to snakebite envenoming, while facing challenges in accessing lifesaving care.
Challenges across the snakebite patient journey:
The prize seeks to improve outcomes for people affected by snakebite by incentivising innovative approaches to overcoming challenges in the patient journey.
Innovations are needed across the patient journey in order to support better community responses, help people receive appropriate care faster, diagnose and assess the type of care they need, and improve the quality of medical care snakebite patients receive:
First aid response
Assessment & diagnosis
Access & logistics
Emergency & supportive care
First aid response:
Immediate, informed, and accurate community and health worker responses with improved first aid tools or methods.
Why?
Critical hours are often lost due to delays in seeking and accessing appropriate medical care. Extreme distances, lack of transport, deterioration of condition during transit to the medical facility, and fragmented referral systems may prevent patients from reaching help in time.
Patients may delay seeking hospital treatment due to a misunderstanding of the seriousness and urgency of snakebites, fear of adverse medical consequences (i.e., amputations or chronic pain), financial barriers, mistrust in the healthcare system, and preference for traditional healers.
Assessment & diagnosis:
Supporting clinical decision-making pathways by understanding patient need and treatment required (e.g., detecting whether venom was injected by the bite or identifying the type of antivenom needed).
Why?
An absence of reliable, affordable diagnostic tools to understand the type of venom and how it is spreading means clinicians rely on symptom observation to assess patients – potentially leading to over-treatment of non-venomous bites, incorrect antivenom administration, and unanticipated treatment needs.
Access & logistics:
Getting people who have been bitten to appropriate emergency medical care, or bringing appropriate care closer to patients faster.
Why?
Most snakebite deaths occur because patients do not reach appropriate medical facilities in time to receive emergency treatment and antivenom.
Even when people reach health facilities in time, some facilities lack basic resources, equipment, protocols, and capacity to manage snakebite emergencies, including appropriate antivenom.
Emergency & supportive care:
Addressing the venom’s effects on the patient, depending on whether it’s cardiovascular toxic (heart and circulation), neurotoxic (nervous system), hemotoxic (blood), cytotoxic (tissue), or myotoxic (muscle).
This could include timely pain management and resuscitation, knowledge of proper antivenom administration, management of adverse reactions, ancillary care, wound management, etc.
Why?
Healthcare workers may not have the specific training, resources or experience, which can affect their confidence in managing snakebites and its complications.
Eligible countries in high-burden settings:
Eligible solutions must be tailored for and implemented in communities where the snakebite burden is felt the most and the unmet need is greatest. These are settings in low and middle-income countries with high snakebite mortality and morbidity rates.
The map below highlights the countries that are deemed as high-burden settings and are eligible under the prize.
