Snakebite vomation is considered a public health problem in Latin America, with an estimated 70, 000 cases annually, but due to underreporting, these numbers may be ev higher.
People most affected are those who live in poor agricultural areas, most oft with m and young people, although accidts occur with all ages, with most bites occurring on the feet and hands. Most accidts happ during rainy periods, wh agricultural activities are started. Indigous communities are also vulnerable due to difficult access to health cters. In Ctral America, Panama records the highest number of annual bites, around 2, 000. In South America it is Brazil, registering 26, 000 to 29, 000, second to Vezuela with 7, 000, and Colombia with 4, 000. Brazil and Costa Rica appartly have higher lethality rates, 0.42% and 0.5% respectively.
Most accidts are caused by snakes of the family Viperidae (Bothrops and Crotalus mainly) with 138 species of viperidae in Latin America. In Brazil, 70-90% of accidts are caused by Bothrops species. The most important are Bothrops asper known as the Fer-de-Lance or Terciopelo, found in Mexico, Ctral America and north South America, Bothrops atrox or Common lancehead edemic to the amazon, and Bothrops jararaca found in Brazil, Argtina and Paraguay. Other important species in South America include B. alternatus, B. mooji, B. neuwied and B. jararacussu. In Brazil, the mortality rate reported by Bothrops is 0.39%, while that of rattlesnakes is 0.98%, Few accidts are caused by Bushmasters (Lachesis), but the mortality rate is high.

Few accidts are caused by elapids (with 78 species) in Latin America, which are represted by coral snakes, of the gera Leptomicrurus (Amazonia) Micruroides (Mexico), Micrurus which is the most widely distributed, and sea snakes, with one species, the Yellow-bellied sea snake, found in Mexico, Ctral America and north South America. Coral snakes represt only 1-2% of elapid accidts in the region, with M. nigrocinctus, M. mipartitus, M. lemniscatus, M. frontalis, M. corallinus and M. spixii being the main ones, while bites by Hydrophis platurus are extremely rare.
Bothrops vom is mainly composed of proteolytic, coagulant, and hemorrhagic activity, causing several symptoms, such as pain, swelling, severe bruising, blisters, and local bleeding (hemorrhage), in severe cases, tissue death can lead to amputation. Systemic effects include severe bleeding, absce of urine production, nausea, vomiting, and low blood pressure, which may lead to shock. Complications such as kidney failure, sepsis, disseminated intravascular coagulation, and bleeding in the brain are the main causes of death
The vom of the South American rattlesnake has three activities, neurotoxic, myotoxic, and low coagulant activity, neurotoxic symptoms are characterized by ptosis, flaccidity of the facial muscles, diplopia, ophthalmoplegia, in rare cases velopalatine paralysis occurs, the myotoxic action is responsible for causing geralized rhabdomyolysis, with muscle pain and myoglobinuria, the coagulant action results in blood being unable to coagulate, and slight gingival bleeding, other manifestations influce malaise, tiredness, sweat, vomiting, nausea, feeling of dry mouth and sleepy aspect. The main complications include acute tubular necrosis with kidney failure and respiratory paralysis.

Lachesis's bite is rare but serious, due to the high amounts it injects, the manifestations are similar to Bothrops, at the site of the bite there is pain and edema, hemorrhagic bubbles, vesicles, and necrosis. Systemic effects include visual disturbances, dizziness, low blood pressure and heart rate, abdominal pain, and diarrhea. In the location of the bite, in severe cases, compartmt syndrome, necrosis, secondary infection, obsessions, and functional deficit may occur.
Symptoms of coral bites can appear in less than an hour or more, at the site the symptoms are mild, with mild pain and paresthesia, systemic manifestations include progressive loss muscle strgth, vomiting, ptosis, ophthalmoplegia, and myasthic facies. Geralized muscle pain may occur, velopalatine paralysis, which results in difficulty in swallowing, and in more severe cases, flaccid paralysis of the respiratory muscles, resulting in severe respiratory failure, with death occurring quickly.
Other gera of medical importance include Bothriechis (palm vipers), which are of arboreal habits, found in Mexico, Ctral America and northern South America.It has a vom of hemotoxic activity, causing local damage, such as severe pain, blisters, bruises and ev gangre.

B. schlegelii is the most widespread and vomous of Bothriechis gus, with hypotsive, procoagulant, necrotoxic, myotoxic and hemorrhagic activity, symptoms include local pain, swelling, ecchymosis, local bleeding and blisters, severe cases including blood incoagulobility, systemic hemorrhage (including bleeding in the brain), necrosis, compartmt syndrome, pressure drop, shock, loss of coagulation factors (disseminated intravascular coagulation), ral failure and multiple organ dysfunction.
Agkistrodon bilineatus, is one of the main causes of bites in its geographic reach, the reported symptoms of the bite include severe pain, local bleeding, edema, nasal and gingival bleeding, petechiae, hematuria, shock, ral failure and necrosis.This corner of the world is a downright doozy for real adventurers. From the bucket-list Inca Trail in Peru to the great glaciers of Argentine Patagonia, the glistening surf beaches of Brazil to the wetlands of Paraguay, there’s loads to get through. But there are some critters you should watch out for when you come…like the most dangerous snakes in South America.
That’s what this guide is all about. It runs through seven of the species that we think every traveler to the land of empanadas and tango dancing needs to keep their eye out for, and it makes for some slightly disconcerting reading.
What Is The Most Venomous Snake In The World? Meet The Inland Taipan
Yep, there are nasty pit vipers that can kill a human in a matter of hours next to dazzling tree snakes that can strike fast next to colossal boas that are able to squeeze their prey to death. They live all over the region, from the Andean mountains to the tropical forests of the Amazon. Let’s begin…
The feared fer-de-lance is up there with the most troublesome snakes on the whole planet. It’s known invariably as the bothrops or, more commonly in Latin America, the terciopelo, and has a range that stretches all the way through the heart of Central America, from the tropical southern reaches of Mexico all the way to the top of the Andes mountains in Colombia, Venezuela, and Ecuador.
The critter can grow to a mammoth 2.5 meters at full adulthood, which places it firmly among the three largest pit vipers in the world. It backs up the beefy size with a massively defensive and aggressive temperament and one of the largest fang-to-body ratios of any creature, anywhere! If that sounds like bad news on the venom front, then that’s because it is. Fer-de-lance vipers are responsible for the most fatal snakebites in their range, killing something near 10% of all human victims.

Perhaps the most telling physical feature of the bothrops is the shape of the head. Like all vipers, it’s large and diamond-like, with two protruding cheeks that come to a distinct nose that’s almost turned up right at the end. The coloring of these bad boys is generally brownish black with alternating triangles running down to the end of the tail.
Eyelash vipers might look pretty but you probably don’t want to get very near. This arboreal palm-pitviper is a tree-dwelling menace, possessing a strong venom and a fast bite. Those that do fall victim to one of its attacks can expect to experience immense pain at the site of contact with the fangs, followed by breathing complications and heart rate fluctuations. Death is rare, but does occur.
There’s no getting around the fact that the eyelash viper is one seriously striking snake. Just as the name implies, they have a series of amazing spiked scales looming over the eyes, which form together to give the appearance of long human eyelashes. Couple that with an incredible color scheme – think mustard yellow the whole way down the body – and you start to see why these are such a popular pet snake among enthusiasts, despite the fact they are deadly!

The eyelash viper is 100% up there with the most dangerous snakes in South America, but it actually only lives in a small part of the continent. The center of its range is in Central America, where it lives all throughout the primeval rainforests of Panama and in the coastal forests of Costa Rica. In South America, it mainly lives in key parts of northern Colombia and Venezuela.
The beasty bushmaster of the south makes its home in the hot and humid equatorial forests that cover huge parts of Ecuador, Peru, and Brazil, but also extends along the northern fringes of the continent as far as Suriname and Brazil. You might also find them out on the Caribbean islands of Trinidad and Tobago.
It’s a feared snake largely because the nature of its venom remains a bit of a mystery. Some say it’s powerful enough to be on par with the formidable fer-de-lance. Others say it’s not quite that bad. However, the fact is that the South American bushmaster has killed humans in the past, so they’re certainly one to watch.
