The following are the most important diseases or complications that may be contributed to by a jellyfish sting:
Endocrine, nutritional, and metabolic diseases (E00-E90).
- Hyperkalemia (potassium excess) due to massive hemolysis from jellyfish sting [caused by cube jellyfish (Cubomedusae; synonym: sea wasp)].
Skin and subcutaneous (L00-L99).
- Skin manifestations: papulovesiculous (“accompanied by nodules (papules) and vesicles (vesicles)”) or pustular (“accompanied by pus-filled vesicles (pustules)”) late reactions (allergic contact dermatitis) (still several weeks; rare) [due to Portuguese galley].
- Pruritus (itching) (often still after months).
Cardiovascular system (I00-I99)
- Sudden cardiac death
Other and unspecified damage due to external causes (T66-T78).
- Anaphylactic shock – potentially life-threatening systemic immune reaction due to allergy.
Symptoms and abnormal clinical and laboratory findings not elsewhere classified (R00-R99)
- Sensory disturbances (often persisting for months).
