In brief: Rare if ever

If you had true cpx after a year of age you likely have lifelong immunity.
People with immune defects or after a bone marrow transplant may be susceptible.Some kids having it under 6mo may be only partially protected, but there are few available to confirm this.Many blister producing illnesses are mislabeled as cpx, so many assume they have it again when misdiagnosed.
