Where you are most likely to die from a snake bite

Of these, at least 200 are medically significant due to their venom’s ability to kill or cause severe harm to humans.

Venomous snakes can be found in nearly every part of the world, but the highest risk of fatal snakebites exists in poor, rural regions of Africa and southern Asia, where medical treatment is often inaccessible.

According to the World Health Organisation (WHO), an estimated 5.4 million people worldwide are bitten by snakes each year. Of these, 1.8 to 2.7 million cases result in envenomation—bites from venomous snakes. 

Each year, between 81,410 and 137,880 people die from snakebites, and three times as many suffer amputations and other permanent disabilities.

Despite its devastating impact, snakebite remains a neglected public health issue, particularly in tropical and subtropical countries across Africa, Asia, and Latin America.

Regions with the highest snakebite cases

• Asia: Up to 2 million people are envenomed by snakes annually, with India being a major hotspot.
• Africa: Around 435,000 to 580,000 snakebites occur each year, many requiring urgent medical attention.

Where are the most venomous snakes?

Certain regions have a higher concentration of deadly snake species, increasing the risk of fatal encounters.

Australia

Australia is home to some of the world's most venomous snakes. A reported 21 of the 25 most toxic snake species are found here, including the inland taipan, considered the most venomous snake on the planet.

Africa

Many African countries, particularly in the eastern and southern regions, are home to highly venomous species such as cobras, mambas, and vipers. The forest cobra, found throughout much of sub-Saharan Africa, and the infamous black mamba (Dendroaspis polylepis), known for its speed and neurotoxic venom, pose significant risks.

India

India is notorious for its venomous snake population, particularly the "Big Four"—the Indian cobra, common krait, Russell's viper, and saw-scaled viper. These species are responsible for a large number of snakebite fatalities in the country. Of 285 snake species in India, the "Big Four" are the deadliest.

Brazil

Brazil’s tropical climate makes it a hotspot for venomous snakes. The Bothrops genus, responsible for more human deaths in the Americas than any other group of venomous snakes, is commonly found in this region.

Reducing snakebite fatalities

While snakebite is still a major risk in many regions of the world, most fatalities and severe side effects can be completely avoided with improved access to healthcare and widely available, potent antivenoms. 

However, preparing the appropriate immunogens (snake venoms) is a major challenge in the production of antivenoms. According to the WHO, very few nations are able to produce snake venoms of a high enough calibre for the production of antivenom.
