Overview
- Civil protection, which issued the first alert Friday for Mezcala and Boca de Apiza, kept warning flags up through the weekend and reported treated stings during the Semana Santa crowds.
- The state operation fielded 49 responders at seven coastal points and logged 10 prehospital cases, two hospital transfers, a located child and a grass fire response.
- Purple flags signal dangerous marine fauna and some beaches also carried red flags that restrict swimming in marked areas to lower the risk of contact.
- Authorities urge visitors not to touch the animal alive or dead, to rinse stings with seawater, avoid rubbing, seek medical care at once and call 911, with hot water immersion advised to ease pain when possible.
- Glaucus atlanticus measures about 3–4 centimeters, floats at the surface, can store Portuguese man‑of‑war toxins and may wash ashore with shifting currents, which is why lifeguards are monitoring for spread to other beaches.
