[1][19] The Palestine viper and Lebetine viper are the most important species. Of these, Bothrops asper is the most important species, partly because it is abundant in lowland areas and partly because it is frequently found in agricultural and pastoral areas where humans work. Specifically, India had the greatest number of deaths, with over 50,000 in 2019. See ST-GPR parameters in the Supplementary Information for further details on ST-GPR hyperparameter weighting equations and covariate selection. There are between 81 410 and 137 Hyg. Vos, T. et al.

Nature Communications (Nat Commun) Naghavi, M. et al. Other than from reaching their natural lifespan, many snakes in captivity die from common illnesses such as mouth rot or from a parasite. For example, there is the Solomons Coral Snake (Salomonelaps par) in the Solomon Islands that has no recorded fatal envenomations, but there are case reports of near-lethal bites35. See Supplementary Fig. J. Venom. [32][33] In regions of Kerala, India, it may be responsible for nearly 10% of venomous bites. People living in densely populated low altitude agricultural areas in the states of Bihar, Jharkhand, Madhya Pradesh, Odisha . 100(7): 693695. Snakebite mortality in India: a nationally representative mortality survey. However, studies have shown that the hump-nosed viper, previously considered essentially harmless and misidentified as the saw-scaled viper, is capable of delivering a fatal bite. https://doi.org/10.1038/s41467-022-33627-9, DOI: https://doi.org/10.1038/s41467-022-33627-9. The World Health Organization (WHO) set a goal to halve snakebite mortality by 2030. states, WHO formally listed snakebite envenoming as a highest priority neglected tropical disease in June 2017.

[39][70], Although not a particularly aggressive species, the horned viper possesses the most potent venom of all European snakes. ST-GPR starts by fitting a mixed-effects linear prior and then fitting a second model based on the weighted residuals between the input data and the linear prior. A change in the condition of a snake's body or scales may be an indicator of a health problem. 89, 145150 (2013). Bull.

Venomous Snakes Bite 7,000-8,000 People in the US Every Year. estimated have significant vulnerability due to poor health system infrastructure and the presence of snakes for which there is no effective antivenom. The strategy focuses on activities in countries and regions where snakebite envenoming occurs, supported by technical units from WHO. Beaked Sea Snake Species Profile (Information Hub) - Snakes for Pets In 2019, the World Health Organization (WHO) set a target to halve the number of deaths and cases of snakebite envenoming by 20304. More than 100,000 people die from snakebites every year. Why is it so PubMed One recent study in the Terai region of Nepal, which is a low-altitude zone with a monsoon climate where agriculture is the primary occupation, found that the mortality rate of snakebite envenomation was 22.4 per 100,000, over five times our estimate for India13. In India, over 64,000 people die of snake bites each yearthe highest globally India accounts for almost 80% of global snakebite deaths yet it is not categorised as a notifiable disease. Directions differ for priors between the GBD 2019 and species-specific model if there was uncertainty if a prior direction would be true for all five venomous species models. [40] In Tasmania and Kangaroo Island, which have a cooler, moister habitat than mainland Australia, the tiger snakes and copperhead snakes inflict the majority of bites. Now let's look at the eye-opening facts about the number of deaths due to snake bites . 5). [75], Southeast Asia's reticulated python, the world's largest snake, is a potentially dangerous species. . BMJ. I Landires is a member of the Sistema Nacional de Investigacin (SNI), which is supported by Panamas Secretara Nacional de Ciencia, Tecnologa e Innovacin (SENACYT).

At the regional level, there was a log-linear relationship between theSocio-demographic Index (SDI) of a region and the regions age-standardized snakebite envenoming mortality rate in 2019 (Fig. While the VR data we used in Sri Lanka likely underestimated the true community-level disease burden, Ediriweera et als study demonstrate the limitations in the ability of verbal autopsy to calculate precise and accurate rates of rare events like snakebite envenomation deaths. At present very few countries have capacity to produce snake venoms of adequate quality for antivenom manufacture, and many manufacturers rely on common commercial sources. Gutirrez, J. M. Understanding and confronting snakebite envenoming: the harvest of cooperation. [65] Over 50% of bites inflicted by sea snakes, which are generally not aggressive, occur when fishermen attempt to remove snakes which have become tangled in fishing nets. Chuat, M. et al. The global burden of snakebite: a literature analysis and modelling based on regional estimates of envenoming and deaths. In addition, lack of regulatory capacity for the control of antivenoms in countries with significant snake bite problems results in an inability to assess the quality and appropriateness of the antivenoms. [28] Agricultural plantations and pastoral areas are involved in approximately 50 to 60% of reported snakebites,[22] while outdoor activities such as collecting firewood and water account for another 20% of bites. The global fight against snake bites - BBC Future Toxicon X 11, 100076 (2021). [18] Although antivenom saves many lives, mortality due to black mamba envenomation is still at 14%, even with antivenom treatment. Mortality from snakebite envenoming has decreased over the last 30 years, however, at an insufficient rate to meet the WHOs 2030 goal. Anim. 14, e0008374 (2020). In Sri Lanka, a recent study by Ediriweera et al. Lancet 391, 22362271 (2018). Studies comparing verbal autopsy community-based studies and official records frequently find that official records undercount the number of deaths that actually occurred10,11,19. 1). Habib, A. G. et al. [22], Mambas, cobras, and some larger puff adder species may claim territories of up to 1 to 2 square kilometres (0.4 to 0.8sqmi), which are used by the snakes for hunting and reproduction. We ran ST-GPR models for snakes, bees, scorpions, spiders, and a fifth other venom category to estimate the rate of death from all five animals for 204 countries, 23 age groups, males and females, for every year between 1980 and 2019, inclusive. We first reviewed all cause of death data that could be mapped directly to snakebites or other venomous animals. Alirol, E., Sharma, S. K., Bawaskar, H. S., Kuch, U. [15] The puff adder is responsible for the most fatalities overall,[16] although saw-scaled vipers (Echis spp) inflict more bites in North African countries, where the puff adder is typically not found. The number of deaths would be much higher if people did not seek medical care. For those bitten by rattlesnakes, 10 . WHO is working closely with a range of partners to ensure the successful implementation of the road map. provided data or critical feedback on data sources. 48, 6275 (2019). This strategy focuses on a 50% reduction in mortality and disability caused by snakebite envenoming Pintor, A. F. V. et al. Algorithms for enhancing public health utility of national causes-of-death data. 1 for a map of data used in the GBD 2019 venomous animal contact model. [29] Most victims who receive treatment by health care professionals have nevertheless delayed seeking medical attention for over 24 hours, and often up to 1 to 2 weeks. 13. [27], Snakebites in Africa are most common in the sub-Saharan countries (scorpion stings are more common in Northern Africa), and typically occur during the rainy season when snakes are more active. The WHO Snakebite Information and Data Platform maps out the habitats of over 200 medically important venomous snakes, out of the 600 venomous snakes and 3000 overall species of snakes.

[65] Although sea snakes are known for extremely potent venom, about 80% of reported bites end up being dry. In 2019, 63,400 people (95% uncertainty interval 38,90078,600) died globally from snakebites, which was equal to an age-standardized mortality rate (ASMR) of 0.8 deaths (0.51.0) per 100,000 and represents a 36% (249) decrease in ASMR since 1990. If there were still more deaths needed for redistribution than properly coded deaths in a location, we aggregated deaths over the GBD region to estimate the proportion of deaths due to each animal and applied that proportion to the redistributed deaths. [2][47], The two-striped forest pit viper is an arboreal snake from the Amazon Basin. PLoS Negl Trop Dis. 8 July 2020 AFP Indian cobras are among the species which kill most people each year An estimated 1.2 million people have died from snake bites in India in the past 20 years, a new study has. [65][67] It is estimated that each year 15,000 to 75,000 fisherman are bitten by sea snakes. In Asia up to 2 million people are envenomed by snakes each year, while in Africa there are an estimated 435 000 to 580 000 snake bites annually that need treatment. [2] However, in the United States, every state except Maine, Alaska, and Hawaii is home to at least one of 20 venomous snake species. Sharma, S. K. et al. Approximately 550 people in Australia are admitted to public hospitals with snake bites each year, and there is an average of two deaths per annum. Source data are provided with this paper for Figs. The results of this detailed technical and laboratory assessment provide regulators and procurement agencies with informed guidance on which antivenoms best suit their needs. The plot shows the top seven regions in terms of age-standardized rates in 2019, all of which had age-standardized mortality rates greater than 0.1 per 100,000. collection and analysis, and integration of snakebite envenoming into the national health plans of affected countries. Within India, Chhattisgarh, Uttar Pradesh, and Rajasthan had the greatest age-standardized death rates, at 6.5 deaths (3.58.4), 6.0 deaths (2.68.0), and 5.8 deaths (3.57.4) per 100,000, respectively. Victims who do reach a hospital often have insufficient access to dialysis, ventilators, and blood transfusions, which are essential to deal with the complications of envenoming18,20. PLoS Negl. [1] The same study estimates that 3,000 to 80,000 envenomations occur in North Africa, although far fewer people, less than 100, die each year. The best-performing models were chosen based on out-of-sample predictive validity. Lancet 392, 673684 (2018). Trop.

[10] Available evidence on the effect of climate change on the epidemiology of snakebite is limited but it is expected that there willll be a geographic shift in risk of snakebite: northwards in North America and southwards in South America and in Mozambique, and increase in incidence of bite in Sri Lanka. However, snake worries don't need to ruin your Bali holiday. It aims to halve death and disability from snakebites by 2030 by investing $136 million in educating communities to prevent bites, making more effective treatments and improving health-care systems. A trawler fisherman who died off the Northern Territory coast is believed to be the first person to be killed by a sea snake bite in Australia in more than 80 years. Trans. Over time, the global age-standardized rate of death has decreased by 36% (249), which shows progress; however, this annual rate of change would be insufficient to accomplish WHOs 2019 goal of halving the burden by 20304. Sea snake bite causes first death in Australia in more than 80 years Trends in snakebite deaths in India from 2000 to 2019 in a - eLife Because there is no reliable reporting system in place and because most victims never report their injury to health care facilities, these numbers are uncertain. Of the 55 species of true sea snakes, most adults are 1-1.5 metres (3.3-5 feet) long, though some individuals may attain 2.7 metres (8.9 feet). Elife. Department of Medicine, B P Koirala Institute of Health Sciences, presentation made at the WHO first Consultative Meeting on Rabies and Envenomings, Geneva, 10 January 2007. 100,000 inhabitants. Epidemiology of snakebites Map showing the approximate world distribution of snakes. Our ensemble modeling framework allowed us to test multiple covariates for their association with snakebite envenoming mortality and provided important insights on the diseases epidemiology. Source data are provided as a Source Data file. Each covariate was given a prior on the direction of its beta coefficient, either positive or negative, if there was a strong prior that it was associated in a positive or negative manner with venomous animal contact mortality. [58] Treatment with antivenom has reduced the mortality from e.g. Lancet https://doi.org/10.1016/S0140-6736(20)30677-2 (2020). Source data are provided as a Source Data file. Luthy, S., Rake, D., Buchanan, T. & Schultze, C. First case report of a near lethal envenomation by a Salomonelaps par (Solomons Coral Snake) in the Solomon Islands. This is equivalent to 68,800 absolute deaths annually (39,100126,000), which is greater than the number of deaths that occurred in 2019, due to forecasted population increases. [37] Most of the Pacific Islands are free of terrestrial snakes, although sea snakes are common in coral reefs. [68] The advent of antivenom and advances in emergency medicine have reduced fatalities to about 3% of snakebite cases. James, S. L. et al. List of fatal snake bites in Australia - Wikipedia In sub-Saharan Africa, over 50% of snakebite injuries are not appropriately treated. Rev. PLoS Negl. [32][33] According to the most conservative estimates, at least 81,000 snake envenomings and 11,000 fatalities occur in India each year, making it the most heavily affected country in the world. Toxins Incl. [15] Approximately 1 million snakebites occur in sub-Saharan Africa each year,[29] resulting in up to 500,000 envenomations, 25,000 deaths and another 25,000 permanent disabilities.[30]. Lines in bold are the snakebite envenoming estimates from the primary statistical analysis pipeline, while dotted lines are the predictions from the forecast regression. Our estimate of 6790 deaths (95% UI 504010,100) in sub-Saharan Africa aligns closely with the meta-analysis by Chippaux, which estimated there were 7331 (51499568) annual deaths7.

Snakebite epidemiology in humans and domestic animals across the Terai region in Nepal: a multicluster random survey. Roberts, N., James, S., Delaney, M. & Fitzmaurice, C. The global need and availability of blood products: a modelling study. The predictive validity of each of the submodels was tested using test-train holdouts, whereby a specific model was trained on 70% of the data and tested on the withheld 30% of data to determine out-of-sample predictive validity, which was quantified using root mean-squared error (RMSE). In conclusion, we provide the most comprehensive and data-driven estimates of the global magnitude of snakebite envenoming mortality to date. Banana plantations are associated with vipers such as night adders, while rubber and palm tree plantations attract elapids, including cobras and black mambas. Weak regulation and the marketing of inappropriate or poor quality antivenoms has also resulted in a loss of confidence in some of the available antivenoms by clinicians, health managers, and patients, which has further eroded demand. [29] In many sub-Saharan countries, poor availability of expensive antivenom contributes to morbidity, and snakebites continue to remain a neglected health problem. Supplementary Table2 shows the life expectancy used in YLL calculations for GBD 2019. Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. However, some estimates put the number at 1.2 to 5.5 million snakebites, 421,000 envenomings, resulting in perhaps 20,000 deaths, but the actual number of deaths may be as high as 94,000. [41], Despite the fact that many Australian snakes have unusually potent venom, wide access to antivenom, which is available for all dangerous species,[38] has made deaths exceedingly rare. J. Venom. All code used for the GBD 2019 analyses is publicly available online at https://ghdx.healthdata.org/gbd-2019/code and custom code for the snakebite envenomation analysis is publicly available online at https://github.com/nlr4002/Snakebite_Envenomation. Particular attention is being focused on the development of a community engagement toolkit, specific interventions to improve access to WHO-recommended antivenoms, improved data Each point represents the age-standardized mortality in a given year from 1990 to 2019 in the region. 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 NGOs2,3. In Eastern sub-Saharan Africa, Ethiopia had 499 deaths (321708) and Kenya had 349 (197603). Under-reporting of snake bite incidence and mortality is common.

By submitting a comment you agree to abide by our Terms and Community Guidelines. The black mamba is the species with the highest mortality rate in every single nation in which it occurs, despite not being responsible for the most numerous snakebites. [8][12] The tropical rattlesnake is another important species. It is the longest snake on the continent and is able to move at 11 kilometres per hour (6.8mph), making it unusually dangerous. & Habib, A. G. The WHO strategy for prevention and control of snakebite envenoming: a sub-Saharan Africa plan. [38] Several venomous colubrids exist in Australia as well, such as the brown tree snake, although they have geographically limited distributions and only very rarely deliver a medically significant bite. Enhydrina schistosa caused over half the bites, including seven of the eight fatal bites.

The weaknesses in some regulatory systems that leads to licensing of ineffective or incorrect products is sometimes coupled to poor procurement practices and inefficient [1] The Malayan pit viper and banded krait are two other species involved in a significant number of venomous bites. Jellyfish Gabriel Bouys / AFP/Getty Images 40 fatalities per year These jellyfish, called Pacific Sea Nettles, possess an extremely painful sting. [21] In forested areas of Guinea, cobras may inflict more than 30% of all venomous bites. The global number of snakebite deaths, although estimated at anywhere from 81,000 to 138,000 by the WHO, is likely even higher than that, according to. About 5.4 million snake bites occur each year, resulting in 1.8 to 2.7 million cases of envenomings (poisoning from snake bites).

India had the greatest absolute number of snakebite envenoming deaths in 2019 at 51,100 deaths (95% UI 29,60064,100), followed by Pakistan (2070 deaths [14702950]). The findings from this study were produced using data available in public online repositories or in the published literature, data that are publicly available on request from the data provider, and data that are not publicly available due to restrictions by the data provider and which were used under license for the current study. List of fatal snake bites in the United States This is a list of some people who were fatally bitten by snakes in the United States by decade in reverse chronological order. Although their venom is the most potent of all snakes, human fatalities are rare because sea snakes are not aggressive, their venom output is small, and their fangs are very short. Securing timely antivenom access across rural areas of the world would save thousands of lives, and greater investment into devising and scaling upthese interventionsshould be prioritized to meet WHOs snakebite envenoming and neglected tropical disease goals. Ralph, R. et al. The funders of the study had no role in study design, data collection, data analysis, data interpretation, or writing of the final report. First, we aggregated the codes by only location and age and applied these proportions to the location-age-sex groups where there were sufficiently properly coded deaths by location and age, but not when stratified by sex. In India, over 64,000 people die of snake bites each yearthe highest Lancet 392, 19231994 (2018). Download: The widespread and common eastern brown snake is one of Australia's most venomous elapids. [19], Even in Europe, measurement of the prevalence and mortality due to venomous snakebite is challenging, and most figures are likely underestimates. public health officials in determining what antivenoms are needed in their country and in drafting relevant national public health policies; national regulators in prioritizing antivenoms for registration and assessing safety, quality, and efficacy of antivenoms to meet national public health needs; procurement agencies in selecting appropriate antivenoms for national treatment needs; antivenom manufacturers in developing plans for production and sale of appropriate antivenoms; clinicians and health care professionals in treating snakebites; and. [74] A large, heavy-bodied, and powerful pit viper, it is the leading cause of fatal snakebites in North America. Few studies on the global disease burden of snakebite envenoming have been conducted. Bites by venomous snakes can cause paralysis that may prevent breathing, bleeding disorders that can lead to a fatal haemorrhage, irreversible kidney failure and tissue damage that can cause permanent disability and limb amputation. N.L.S.R., R.D., L.D., S.L.J., D.M.P., S.I.H., T.V., and K.L.O. Preventing and treating the problem is complex and requires collaboration among the fields of public health, medicine, ecology, and laboratory science. Stevens, G. A. et al. Poor data on the number and type of snake bites have led to difficulty in estimating needs, and deficient distribution policies have further contributed to manufacturers reducing or stopping production or increasing the prices of antivenoms.
