Welcome to the Second Edition of the Global Psoriasis Atlas


Our research indicates that there are more than 60 million people living with psoriasis globally.


Psoriasis is a systemic disease that affects people physically and psychologically and is associated with other important medical conditions.


One of the aims of the GPA is to understand the number of people around the world who have psoriasis and the care and treatment available to them.


Explore and share the Global Psoriasis Atlas and join us in our efforts to ensure that people are provided with the best available data on psoriasis globally.
