How to Manage Seabather’s Eruption

Seabather’s eruption is an extremely itchy skin rash caused by a hypersensitivity reaction to the larval-stage of various marine organisms. These marine organisms have nematocysts, stinging cells, which sting the swimmer and cause the pruritic dermatitis. It occurs in the bathing suit covered areas of the skin, rather than the exposed area, and befalls in the sea, thus its name seabather’s.
