Emergency First Aid Manual – Snake Bite and Animal Bite

Snake bites

Venomous snakes are snakes that have poisonous fangs and venom glands. Snake bites can be identified by two large puncture wounds.

First Aid

  1. Restrict movement of the person and the area that has been bitten.
  2. Use a cloth to wrap the area below and above the bite site, up until the joint of the body closest to the bite site. Wrap it tight enough so that you may still be able to slide a finger under the bandage.
  3. Support the area of the bite with a wooden or any hard panel to create a temporary splint in order to restrict movement. Keep the bitten area below the heart level.
  4. Immediately send the victim to the hospital or call the Emergency Medical Services.


  1. Do not attempt to suck out the venom by mouth.
  2. Do not tie a string or band above the bite site.

Animal bites

If you are bitten by a dog or any other mammal, such as a cat, cow, squirrel, horse, pig or a bat and have a wound, you may be exposed to the rabies infection which may be passed through the saliva of the animal. The wound may contain a bacterial infection. Even a human bite may cause bacterial infection.

First Aid

  1. Washing and cleaning the wound with soap and copious amount of water can reduce the exposure to rabies and bacterial infection.
  2. Clean the wound with an antiseptic medication, containing 70% alcohol or Povidine (Betadine). Do not sew the wound.
  3. If there is bleeding in the wound or if you have come in contact with the animals (they have licked your eyes or your lips), then immediately consult the physician for a possible anti-rabies vaccination or serum.
  4. Keep the animal in the cage for at least 10 days to observe the behavior. If the animal cannot be kept in a cage or dies, bring the animal for examination.
  5. If the animal cannot be kept in a cage or escapes, it is recommended to get an anti-rabies vaccination or serum.

Places to send the animal carcass for rabies testing:

  1. Queen Saowapha Memorial Institute, Thai Red Cross
  2. Siriraj Hospital
  3. Development of Livestock Department in Bangkok and the provinces
  4. Chiang Mai University
  5. Public Health Department in Bangkok and the provinces
