Snakes of Bangladesh

A 2022 national survey estimated that around 400,000 people are bitten by snakes in Bangladesh each year and about 7,500 of them die. The monocled cobra causes most cobra bites, kraits cause many bites and deaths, green pit vipers cause many bites but few deaths, and Russell's viper is restricted to the west and south.

First aid in BangladeshGeneral first-aid steps

  • Australia

    Emergency000

    Australian first aid for snakebite uses a pressure immobilisation bandage and splint, and advises not washing the bite.

  • Bangladesh

    Emergency999

    A 2017 study noted that the Indian polyvalent antivenom used in Bangladesh is not made from the venoms of local species such as the monocled cobra, and it did not prevent local tissue damage from cobra bites.

  • Brazil

    Ambulance192Emergency193

    Antivenom is free in Brazil's public health system (SUS), but it is only given in hospital, at reference hospitals chosen by each state.

  • India

    Ambulance108Emergency112

    Indian polyvalent antivenom is raised against the 'Big Four' and may not neutralise some regional species, such as the monocellate cobra in the North-East and the hump-nosed pit viper in the south-west.

  • Indonesia

    Ambulance119Emergency112

    Indonesia's own antivenom, made by Bio Farma, is raised against only three species (Javan spitting cobra, banded krait and Malayan pit viper), so it may work poorly for bites by other snakes such as green pit vipers.

  • Kenya

    Emergency999

    Antivenom is usually stocked only at hospitals and some health centres, so people bitten in rural areas often need to be referred, and delays are common.

  • Mexico

    Emergency911

    Mexico's public health system uses two anti-viper antivenoms; one is made from the venoms of the terciopelo and the Mexican west coast rattlesnake.

  • Nepal

    Ambulance102Emergency100

    100 is the police emergency number; call 102 for an ambulance.

  • Nigeria

    Emergency112

    Antivenoms made from Nigerian snake venoms (EchiTAb G and EchiTAb-Plus-ICP) have proved effective in clinical trials, while some imported antivenoms made from non-African snake venoms have proved ineffective.

  • Pakistan

    Emergency1122

    Rescue 1122 handles ambulance and fire emergencies; the police number is 15.

  • Philippines

    Emergency911

    The only antivenom made in the Philippines is Philippine Cobra Antivenom, raised against the Philippine cobra; there is no locally made antivenom for pit viper bites.

  • South Africa

    Ambulance10177Emergency112

    112 works for all emergencies from a mobile phone; 10177 is ambulance and fire, and 10111 is police.

  • Sri Lanka

    Ambulance1990Emergency119

    119 (or 118) is the police emergency number; call 1990 for an ambulance.

  • United States

    Emergency911

    For free, expert 24/7 advice you can also call Poison Help on 1-800-222-1222, but call 911 in an emergency.

Snakes to keep away from

Look-alikes

Dangerous or harmless?

Harmless snakes are often killed because they look like dangerous ones. Learn the differences, and still never handle a snake.

Spot the difference
Common krait coiled on bare earth and dry leaves, showing thin white bands on a glossy black body
Medically significant

Common krait

Bungarus caeruleus

Bands
Thin white bands, often in pairs. They fade towards the head.
Colour
Glossy black or bluish-black, with a row of enlarged scales along the middle of the back.
Head
A dark head with a white upper lip.
Common wolf snake coiled on reddish soil, showing a dark brown body with white crossbands that widen on the sides
Non-venomous

Common wolf snake

Lycodon aulicus

Bands
White bands that widen or fork on the sides.
Colour
Brown or greyish-brown.
Head
A pale patch behind the head, and a flattened snout that juts past the lower jaw.

Differences from Smith (1943), cited in both profiles. They help you learn the two apart; they are not a safe basis for handling any snake.
