what snake kills the most people

According to multiple sources, the snake that kills the most people is either the Asian Cobra group (Naja sp.) and/or Saw-scaled vipers (Echis sp.) . However, there is no way to know which for sure. A recent study estimated that there are around 421,000 snake envenomations worldwide each year and of those bitten, 20,000 a year die. The same study warns, however, that given the underreporting that is likely, it is possible there are as many as 1.8 million envenomations worldwide per year and up to 94,000 deaths. The saw-scaled viper (Echis carinatus) may be the deadliest of all snakes, since scientists believe it to be responsible for more human deaths than all other snake species combined. Its venom, however, is lethal in less than 10 percent of untreated victims, but the snake’s aggressiveness means it bites early and often. The Indian cobra (Naja naja) is another dangerous snake that kills about 15,000 people annually. The "Big 4" snakes, which are responsible for 75% of all bites and perhaps a greater number of fatal bites, are currently Russell’s viper, common krait, Indian cobra, and Indian saw-scaled viper.
