Eczema cannot be prevented, but progression of symptoms may be decreased by avoiding allergens that seem to cause flare-ups. Controlling stress or anxiety-producing situations may also decrease risk of eczema flare-ups.
Long-term effects of eczema include infection and scarring. Other long-term effects may include emotional frustration from scarring. Children will usually outgrow eczema by about 6 years of age, although sometimes improvement is not seen until puberty or adulthood. Long-term effects can usually be lessened with early treatment.
Eczema is not contagious, but if the lesions become infected, the organism causing the infection may be contagious.
