Thus, any larvae trapped under swimming bathers or caps can cause toxins to be released. The skin develops an allergic response to the toxin and a rash forms. Swimming clothes contaminated by the stinging cells can produce a reaction even weeks after they have been washed and dried as the toxins are still able to be released from trapped stinging cells. Rubbing, showering in fresh water and wearing contaminated bathing suits for a long time after getting out of the water tend make the rash worse. Symptoms other than those involving the skin may occur occasionally.
