Seabather's eruption

From Wikipedia, the free encyclopedia

Seabather's eruption (locally known as sea lice) is an immune response to the larval stage of the thimble jellyfish. This reaction occurs mainly in Florida, due to the proximity of the Gulf Stream to the state. It should be noted that animals can be affected as well, and that a cortisone solution for humans can be used on dogs. Recently found severe cases in Thailand.

[edit] Identification

The reaction is identified by severe itching around small red papules 1mm to 1.5cm in size usually found around areas where swimsuits were in contact with the skin or hair, but not necessarily.

[edit] Treatment and symptoms

Treatment does not require a doctor's attention unless the case is severe, with most affected using a topical anti-itch cream (diphenhydramine) and a cortisone solution (hydrocortisone). Do not scratch the area, and avoid any clothing that may irritate the affected area; scratching will result in localized swelling and intense itching. Symptoms arise minutes after contact and can last up to 2 weeks but usually last only a few days.

It is best to remove clothing before rinsing in cold water or drying off. Inactivated larvae may react to fresh water or lack of water, thus activating.The contaminated swimsuit should be machine washed, and dried in warm air.
