The situation remains tense at beaches across Euboea, with a new incident reported at the beach of Agios Mina. Two women were affected by purple jellyfish stings, suffering from blisters, severe redness, and persistent pain—typical symptoms of such encounters. Additionally, a man described his painful experience upon being stung by a purple jellyfish while swimming off a beach in Chalcis.
Authorities are urging swimmers to remain vigilant. If jellyfish or tentacles are spotted in the water, entering the sea should be avoided. In case of a sting, the affected area should be rinsed exclusively with seawater—never freshwater—and rubbing should be avoided. The use of antihistamines or corticosteroid creams should only be done under medical supervision.
Intense presence of purple jellyfish has been recorded mainly in Chalcis and the northern Evoikos Gulf, according to the Greek Biodiversity Observatory. Northern Euboea faces a serious issue as it serves as an outlet from the Pagasitic Gulf into open waters, where significant jellyfish populations have also been observed, particularly along eastern coasts. The spread has reached as far as the Northern Sporades islands, with confirmed sightings on Skiathos and Skopelos.
