Psoriasis has a disease prevalence of 0.44-2.8 per cent in India and 2 to 3 % worldwide. There are many gaps in research to fully understand the epidemiology, aetiology, association with comorbidities, environmental variations, that all hinder optimal delivery of healthcare services in a personalized manner.  There is a need for better quality data on incidence and prevalence of psoriasis to understand better the size and distribution of the problem.
