Key Takeaways:
- The jellyfish stings can cause significant allergic reactions in some people, with symptoms appearing hours or even a day after the initial sting.
- Outbreaks of the painful pest typically occur at this time of year, in calm weather with warm seas.
- Treatment options include antihistamine, calamine lotion, hydrocortisone, and local anaesthetic cream, but the choice of treatment depends on the severity of the stings.
- It is essential to get out of swimming gear as soon as possible and rinse it in fresh water with soap to prevent further stings.
- The jellyfish are microscopic and almost impossible to see, but can get trapped in togs or tangled in body hair, releasing a sting when faced with pressure, friction, or a change from salt to fresh water.
Introduction to the Problem
The recent outbreak of jellyfish stings at Ruakākā Beach has left many swimmers with painful and itchy rashes. The jellyfish, which are microscopic and almost impossible to see, can cause significant allergic reactions in some people. According to Waipū Pharmacy pharmacist Brenda Wells, the outbreaks of the painful pest are marked by their sudden start, with people suddenly coming into the pharmacy seeking relief. The stings typically do not show up until the first evening or next day, making it difficult for swimmers to associate their symptoms with the jellyfish.
Causes and Conditions
Orrs Unichem Pharmacy Ruakākā pharmacist Warren Greene explained that the outbreaks tend to happen in calm weather with warm seas. The current sea temperature in Bream Bay is 22.44C, which is ideal for the jellyfish to thrive. Greene noted that the jellyfish are not as prevalent when there is a lot of surf, as the waves help to wash them away. The calm and warm conditions at Uretiti beach, in particular, have created an ideal environment for the jellyfish to multiply. Earth Sciences New Zealand Ruakākā aquaculture facility operations manager Steve Pither confirmed that the sea temperature is currently conducive to the jellyfish’s growth.
Personal Experiences
Ruakākā Beach resident Hanna Modrich shared her experience of how her daughter Annabelle, 8, was badly affected by the jellyfish stings after competing in a junior surf lifesaving competition at the beach on Saturday. Annabelle was stung all over her body, while her younger sister Nina, 5, was also stung, although not as badly. Modrich’s young niece was also stung after swimming at the same beach on Saturday. Modrich is now treating the girls with ice packs and calamine lotion. She grew up at Ruakākā Beach and has lived there with her family for the last eight years, but has never seen the jellyfish before.
Symptoms and Treatment
Greene explained that people are differently affected by the jellyfish stings, with some swimmers not being stung at all, while others may experience intensely itchy raised red welts and rashes. The symptoms can range from small, red, raised bumps that are itchy but not too bad, to more severe reactions. Wells noted that treatment options include antihistamine, calamine lotion, hydrocortisone, and local anaesthetic cream, but the choice of treatment depends on the severity of the stings. It is essential to get treatment advice to ensure the best course of action.
Prevention and Precautions
American research scientist Dr Anita Freudenthal, who visited New Zealand to study the tiny pest, explained that the jellyfish often get trapped in togs or tangled in body hair and release a sting when faced with pressure, friction, or a change from salt to fresh water. To prevent further stings, it is crucial to get out of swimming gear as soon as possible and rinse it in fresh water with soap. Greene also advised swimmers to rinse their togs in fresh water and use soap when they get home to prevent the jellyfish from releasing their stings. By taking these precautions, swimmers can minimize the risk of getting stung and reduce the severity of the symptoms if they do get stung.
Conclusion
The recent outbreak of jellyfish stings at Ruakākā Beach is a reminder of the importance of being aware of the potential risks associated with swimming in the ocean. By understanding the causes and conditions that contribute to the jellyfish’s growth, swimmers can take precautions to minimize their risk of getting stung. If stung, it is essential to seek treatment advice and follow the recommended course of action to alleviate symptoms. By working together, we can reduce the impact of these painful pests and enjoy the ocean safely.
