<s>[INST] What are the potential complications? [/INST] Most cases of scarlet fever have no complications at all.  However, in the early stages, there is a small risk that you might get one of the following:
Ear infection
Throat abscess
Pneumonia
Inflammation of the sinuses (sinusitis)
Meningitis.
On rare occasions, at a later stage the disease could lead to:
Bone or joint problems
Liver damage
Kidney damage
Acute rheumatic fever (which can damage the heart).
Patients, or their parents, should keep an eye out for any symptoms which might suggest these complications in the first few weeks after the main infection has cleared up and, if concerned, seek medical help immediately.
