Prevalence

US Cases: 210,000 - 260,000 [Izmirly 2021]. Note that this is for systemic lupus only (SLE). Many estimates of “lupus” include patients with less severe forms (cutaneous/discoid lupus).

Onset of SLE is usually after puberty, typically in the 20s and 30s, with 20% of all cases diagnosed during the first 2 decades of life.
