At certain times of the year (summer and rising winds) and for different reasons, there is an important arrival of populations of jellyfish carried by the sea currents, altering or even preventing walks or bathing on beaches (violet flag).
Jellyfish are marine animals, invertebrates and gelatinous, have a bell shape and arms called tentacles. There are multiple species and in our coasts the most common are the genus Physalia (Carabela Portuguesa). Inside the tentacles contain substances (poison) that release to capture prey or as a defense.
In general, with few exceptions, bites are not usually severe. Only contact with live or dead jellyfish or body remains produces immediate pain, burning and intense itching in the area of contact with redness, inflammation, appearance of vesicles even bleeding. In rare cases cramps, nausea and vomiting. Scarcely frequent seizures or neurological depression. Everything disappears within a few hours and can sometimes last for days.
The vast majority of jellyfish accidents occur from accidental contact during bathing, when they are stepped on or manipulated, usually by children.
1.- Clean the affected area with sea water or „jet“ physiological serum. Never use fresh water, ammonia, or urine.
2.- Do not rub or scratch the area with the towel or sand. Remove the tentacles if any are left attached, with tweezers.
3.- Apply ice 15-20 minutes never directly, protecting the area with gauze or cloth.
4.- Afterwards apply corticosteroid cream for inflammation. An antihistamine may be needed for itching and soothing to improve the pain.
5.- If the pain is very intense or the situation worsens, you should go to a medical center.
