Answer

A study of 79 patients with urticaria detected anti-HCV antibody in 24% and HCV RNA in 22%. Genotype 1b was present in 71% of patients; genotype 2a, in 24%; and genotype 2b, in 6%. In patients with HCV, urticaria tends to last longer than the typical few hours, is associated with worse liver status, and leaves a brown stain. Clinical findings of urticaria are identical to those of hives.
