Annually, throughout the world, it is estimated there are a minimum of 1 to 2 million snakebite "incidences." This number includes bites by non-venomous species. Of that number roughly 50,000 to 60,000 bites result in fatalities.
The country that has the largest number of snakebite deaths annually is the tiny island of Sri Lanka.
Each year in the United States there are approximately 45,000 snake bite incidences, including non-venomous bites. Only about 8000 of that number are venomous snake bites but a mere 9 to 15 people die.
The Most Dangerous Snakes that kill the most people according to the geographical locations are as given below : -
In the United States the coral snake has a very toxic venom but has killed few people because it is small, secretive and gentle. The most dangerous are the rattlesnakes like the Eastern and Western Diamondbacks. These rattlesnakes are large, have large venom glands, are relatively common, and are more likely to hold their ground and bite.
In Africa common Egyptian Cobras, Saw-scaled Vipers, and Puff Adders would be the most dangerous.
In Asia the common Cobra and the Russell's Viper are the snakes that kill the most people.
