Who is affected by psoriasis
Psoriasis
is more common in adults than in children.
It is equally common in women and men.1
Psoriasis affects:
- 1% to 3% of people throughout the world.2
- About 2% to 3% of people in the United States.
Every year about 150,000 people in the U.S. are newly diagnosed with
psoriasis.1
- Some cultures more than
others.3 For example, it is common in Japanese people
but not in native North Americans or native South Americans. It is uncommon
among blacks in tropical areas, but it is seen more often among blacks in
temperate areas, such as in the United States and Europe, where the year-round
climate is moderate.
