How to care for a jellyfish sting

Anyone is at risk for a jellyfish sting when spending time in the beach. The tentacles of jellyfish have stinging cells that cause injury to humans and animals and the severity depends on the type of jellyfish the person comes in contact with.

Once a jellyfish sting occurs, they release thousands of tiny barbs that hook into the skin and release venom. The venom causes slight discomfort and a painful rash. Sometimes, the venom of jellyfish can affect the entire body.

Symptoms of jellyfish sting

  • When swimming, observe the warning signs on the beach.
  • When swimming, make sure that a lifeguard is nearby.
