Jellyfish are aptly named. Their gelatinous, cloudy bodies look like globs of jelly. But the ugly body is not what's dangerous. The dangerous parts are the cells that adhere to their dangling brownish tentacles; those cells contain a poisonous and vicious venom that causes a painful sting in humans.
Jellyfish “epidemics” are usually cyclical, occurring at specific times during the summer. One day, you are swimming in clear water, and the next day the water is cloudy with floating jellyfish, adrift in the waves. Avoiding jellyfish is the best solution, but sometimes a long tentacle can get you even if the jellyfish body is far away. Symptoms of a jellyfish sting can include:
| Immediate searing pain | Swelling at the site |
| A red rash | Nausea and vomiting |
| Cramps | Shock (in severe cases) |
| Breathing problems (in severe cases) |
It's always a good idea to have a physician check out fish bites, but not every bite is an emergency that requires immediate profession attention. If the person is suffering from shock, of course, help must be swift. Further, a sting on the face, especially near the eyes or the neck, can cause dangerous swelling, which should always receive quick medical attention. If you see signs of fever, swelling, or other atypical symptoms, get medical help. If there's nothing more than a painful sting, a topical antibacterial ointment and dressing might be all that's needed.
If someone gets stung by a jellyfish, follow these steps to provide first aid for the wound:
If the pain is very intense, try rinsing the bite site with some baking soda and water after you've followed your first aid steps. It can help decrease the pain until medical help arrives.
Even if the sting is mild and the victim feels fine soon after the episode, it's good to keep watch for up to three days later. Jellyfish stings can get infected days after the incident. The best prevention? Antibacterial ointment—once the stinging sensation is gone. Before then …ouch!
