Answer

Answer

The guttate form of psoriasis is relatively uncommon in the United States, occurring in less than 2% of the psoriatic population. International surveys on the guttate form of psoriasis among patients with psoriasis have found a wide range of prevalences, from 1.6-44%. A 2009 study has shown that the prevalence of psoriasis correlates with the distribution and mortality of streptococcal epidemics. [14]
