How to treat a Box Jellyfish Sting?

box jellyfish
Box jellyfish, named for their body shape, have tentacles covered in biological booby traps known as nematocysts – tiny darts loaded with poison. People and animals unfortunate enough to be injected with this poison may experience paralysis, cardiac arrest, and even death, all within a few minutes of being stung.
How does a Box Jellyfish sting a person?

Box jellyfish is a transparent, boxed-shape sea jelly that can measure up to a foot  with tentacles that can reach up to 10 feet. Each tentacles has stinging cells that shoot venom to the skin once it latches to whichever body part the jellyfish sticks to. Box jellyfish are difficult to see in the water due to their transparency. That’s the reason why people get stung once on the beach. Sometimes they get beached and people don’t realise that they already step into one. The sting can be very fatal to children that can cause cardiac arrest in a few minutes.

What are the symptoms?
  • Red and swelling on where the tentacles attached to the area
  • Can feel severe burning and sting
  • Can cause unconsciousness
  • Pain in the back, abdominal area and chest
  • Elevated blood pressure and heart rate
  • Can cause cardiac arrest in severe cases
How to treat a box Jellyfish Sting?
  • If stung in the water, exit the water right away
  • Rinse the area using vinegar. Using vinegar can prevent the stingers from firing venoms to your skin
  • Call emergency service right away or 000
  • Monitor vital signs of the person. If unconscious and not breathing, begin CPR
DO NOT:
