Around the World and Jellyfish on your beach

---

Jellyfish flags are a type of warning system used by beaches to inform visitors of the presence of jellyfish in the water. These flags are typically a solid purple color, although some beaches may use different colors or symbols to indicate different types of water hazards.

When a jellyfish flag is raised, it means that jellyfish have been spotted in the water and that visitors should exercise caution if they choose to enter the water. Some beaches may also post additional warnings or advisories regarding the type of jellyfish present and any potential hazards they may pose.

It's important to take jellyfish warnings seriously and follow any instructions provided by lifeguards or other beach officials. If you do decide to enter the water when a jellyfish warning is in effect, be sure to take appropriate precautions to avoid being stung, such as wearing protective clothing and avoiding areas where jellyfish are concentrated.

 If you encounter jellyfish on a beach, there are several important things you should know:

1. Identification: It's important to identify the type of jellyfish you have encountered. Not all jellyfish are harmful to humans, but some can cause painful stings or even be life-threatening.
2. Safety precautions: To avoid getting stung, it's recommended that you wear protective clothing, such as long-sleeved shirts and pants. You can also consider using a barrier cream or spray to protect your skin.
3. First aid: If you do get stung by a jellyfish, it's important to seek medical attention immediately. Rinse the affected area with vinegar or saltwater, but avoid using freshwater as it can cause the jellyfish stingers to release more venom.
4. Prevention: You can reduce your chances of encountering jellyfish on a beach by paying attention to warning signs or advisories, avoiding swimming in areas known to have high jellyfish populations, and refraining from touching or picking up any jellyfish you see on the beach.
5. Environmental impact: Jellyfish populations can be affected by human activities such as pollution and overfishing, which can lead to more frequent and severe jellyfish blooms. It's important to be aware of our impact on the environment and take steps to minimize it.

If you have been stung by a jellyfish, the first thing to do is to ensure you are not having severe or life-threatening side effects such as difficulty breathing or swelling of your lips, throat or tongue. If any of these occur, it is important to call 911 or head to the nearest emergency room right away. It is also important to seek medical attention right away if you develop fevers, are feeling sick (e.g. chills, nausea, vomiting), or if the sting occurs in (or near) your eyes or mouth.

If you don’t experience any of the warning signs above, it is likely safe to try to care for the sting yourself.

• Start by rinsing the area with sea water to rinse off the venom (of note: using fresh water can actually make the pain and irritation worse).
• Using gloved hands or tweezers, remove any tentacles you can see.
• Follow by washing the area with vinegar to help stop the stinging. Keep in mind there are a few species of jellyfish where vinegar can make the stinging worse, so do this cautiously.
• After completing these steps, you can use over-the-counter hydrocortisone cream (alternatively, calamine lotion), ibuprofen and diphenhydramine (aka Benadryl) to help soothe pain, itching, and irritation.

Note, while the pain and irritation usually improve within 12-24 hours, the redness and rash can persist for weeks! Some stings may even leave a scar.
