• Psoriasis is the most prevalent autoimmune disease in the U.S.
• According to current studies, as many as 7.5 million Americans—approximately
2.2 percent of the population--have psoriasis.
• 125 million people worldwide—2 to 3 percent of the total population—have psoriasis, according to the World Psoriasis Day consortium.
• Studies show that between 10 and 30 percent of people with psoriasis also develop psoriatic arthritis.
• Psoriasis prevalence in African Americans is 1.3 percent compared to 2.5 percent of Caucasians.

Quality of life for Psoriasis Patients

• Psoriasis is not a cosmetic problem. Nearly 60 percent of people with psoriasis reported their disease to be a large problem in their everyday life.
• Nearly 40 percent with psoriatic arthritis reported their disease to be a large problem in everyday life.
• Patients with moderate to severe psoriasis experienced a greater negative impact on their quality of life.

Age of onset
• Psoriasis often appears between the ages of 15 and 25, but can develop at any age.
• Psoriatic arthritis usually develops between the ages of 30 and 50, but can develop at any age.

Severity of Psoriasis

• The National Psoriasis Foundation defines mild psoriasis as affecting less than 3 percent of the body; 3 percent to 10 percent is considered moderate; more than 10 percent is considered severe. For most individuals, your hand is about the same as 1 percent of the skin surface. However, the severity of psoriasis is also measured by how psoriasis affects a person's quality of life.
• Nearly one-quarter of people with psoriasis have cases that are considered moderate to severe.

Cost of Psoriasis

• Total direct and indirect health care costs of psoriasis for patients are calculated at $135 billion annually in the U.S., or up to $26,000 per person. Direct costs, which include the cost of treatment and doctor's visits, can be as high as $8,000 each year per person. The cost of coping with comorbidities, such as diabetes, heart disease and depression, reaches almost $5,000 per person annually.
• Indirect costs, which take into account absences from work, or lost productivity on the job due to psoriasis, were estimated to be upwards of $4,000 per person annually—or as much as $35.4 billion for the nation.
• Approximately 60 percent of psoriasis patients missed an average of 26 days of work a year due to their illness
