The condition is more common in young adults, and prevalence appears to peak in adults aged 26–28 (up to 20%). The vast majority of cases are reported to be mild, and proportionally few individuals seek medical attention regarding the condition. History
Cholinergic urticaria was first described by Duke in 1924 as "urticaria calorica". The term cholinergic is derived from the finding that hives similar to those of CU can be evoked using cholinergic agonists (e.g. methacholine). See also
