This publication describes the first WHO public-benefit Target Product Profiles (TPPs) for snakebite antivenoms. It focuses on antivenoms for treatment of snakebite envenoming in sub-Saharan Africa. Four TPPs are described in the document:
Broad spectrum Pan-African polyvalent antivenoms: products ...that are intended for widespread utility throughout sub-Saharan Africa for treatment of envenoming irrespective of the species of snake causing a bite. Monovalent antivenoms for specific use cases: for products for a single species (or genus) of snake (e.g., boomslangs or carpet viper antivenoms).
Syndromic Pan-African polyvalent antivenoms for neurotoxic envenoming: products that are intended for treatment of envenoming by species whose venoms are neurotoxic. Syndromic Pan-African polyvalent antivenoms for non-neurotoxic envenoming: products for snakebite envenoming where the effects are largely haemorrhagic, necrotic or procoagulant.

Snake-bites are well-known medical emergencies in many parts of the world, especially in rural areas. Agricultural workers and children are the most affected. The incidence of snake-bite mortality is particularly high in South-East Asia. Rational use of snake anti-venom can substantially reduce mort...ality and morbidity due to snake bites. These Guidelines are a revised and updated version of similar guidelines published by the WHO Regional Office in South-East Asia in 1999. These guidelines aim to promote the rational management of snake-bite cases in various health facilities where trained health functionaries and quality snake antivenom are available.

Snakebite envenoming affects millions of people worldwide annually and is a significant source of mortality. Preventing and treating the problem is complex and requires collaboration among the fields of public health, medicine, ecology, and laboratory science. After being removed from the category A... neglected tropical disease (NTD) list in 2013, snakebite envenoming was reinstated in 2017 in response to antivenom shortages and advocacy from researchers and international NGOs. In 2019, the World Health Organization (WHO) set a target to halve the number of deaths and cases of snakebite envenoming by 2030.

Snakebite envenoming is a serious public health problem in Central America, where approximately 5,500 cases occur every year. Panama has the highest incidence and El Salvador the lowest. The majority, and most severe, cases are inflicted by the pit viper Bothrops asper (family Viperidae), locally kn...own as ‘terciopelo’, ‘barba amarilla’ or ‘equis’. About 1% of the bites are caused by coral snakes of the genus Micrurus (family Elapidae). Despite significant and successful efforts in Central America regarding snakebite envenomings in the areas of research, antivenom manufacture and quality control, training of health professionals in the diagnosis and clinical management of bites, and prevention of snakebites, much remains to be done in order to further reduce the impact of this medical condition. This essay presents seven challenges for improving the confrontation of snakebite envenoming in Central America. Overcoming these challenges demands a coordinated partnership of highly diverse stakeholders though inter-sectorial and inter-programmatic interventions.

As part of its 2019–2030 global strategy for the prevention and control of snakebite envenoming, WHO is launching a new Snakebite Information and Data Platform. This is the result of collaboration between the Departments of Control of Neglected Tropical Diseases (WHO/NTD) and Data Delivery for Imp...act & Analytics (WHO/DDI).
With support from the WHO GIS Centre for Health, the platform is developed with a new generation of ArcGIS software. It comprises advanced tools for managing, analyzing, and visualizing updated multi-sourced data, providing an interactive and participative user experience. It includes updated range maps of all medically important venomous snakes, other relevant information, and an integrated antivenom products database.

Snakebite envenoming is a neglected tropical disease (NTD) that is responsible for enormous suffering, disability and premature death on every continent. As over 5.8 billion people are at risk of encountering a venomous snake, it is not surprising but no less tragic that almost 7400 people every
da...y are bitten by snakes, and 220–380 men, women and children die as a result, adding up to about 2.7 million cases of envenoming and 8100–138 000 deaths a year.

Snakebite is an acute life threatening time limiting medical emergency. It is a preventable public
health hazard often faced by rural population in tropical and subtropical countries with heavy
rainfall and humid climate.

Snakebite envenoming constitutes a serious medical condition that primarily affects residents of rural communities in Africa, Asia, Latin America, and New Guinea. It is an occupational, environmental, and domestic health hazard that exacerbates the already impoverished state of these communities. Co...nservative estimates indicate that, worldwide, more than 5 million people suffer snakebite every year, leading to 25,000–125,000 deaths, while an estimated 400,000 people are left with permanent disabilities.

In one of his final essays, statesman and former United Nations secretary general Kofi Annan said, ‘Snakebite is the most important tropical disease you’ve never heard of’. Mr. Annan firmly believed that victims of snakebite envenoming should be recognised and afforded greater efforts at impro...ved prevention, treatment, and rehabilitation. During the last years of his life, he advocated strongly for the World Health Organisation (WHO) and the global community to give greater priority to this disease of poverty and its victims.

Snakebite envenoming is a potentially life-threatening disease that typically results from the injection of a mixture of different toxins (“venom”) following the bite of a venomous snake. Envenoming can also be caused by venom being sprayed into a person’s eyes by certain species of snakes tha...t have the ability to spit venom as a defence measure. Not all snakebites result in envenoming: some snakes are non-venomous and venomous snakes do not always inject venom during a bite. About 50–55% of all snakebites result in envenoming. Snake venoms are complex mixtures of protein and peptide toxins, varying from one species to another, and even within species. The toxins in snake venoms are evolutionarily adapted to interact with a large variety of cellular targets in the organisms exposed to them. In humans and animals, snakebite envenoming affects multiple organ systems (depending on the particular species of snake and the classes of toxins present in the venom) and can cause, among other things: haemorrhage and prolonged disruption of haemostasis, neuromuscular paralysis, tissue necrosis, myolysis (muscle degeneration), cardiotoxicity, acute kidney injury, thrombosis and hypovolaemic shock.

This update of the Guidelines for poison control, entitled Guidelines for establishing a poison centre, reflects the development of the role of poison centres in public health and the sound management of chemicals, described in section 1, and the opportunities provided by new technology. Assessments... carried out under the IHR show
continuing gaps in capacity for managing chemicals (2). In particular, many countries still lack access to poison
centre services (3). There is therefore demand for updated guidance.
