Psoriasis Is Not Contagious: Common triggers and treatment options
Psoriasis is a chronic condition in which an overactive immune system causes skin cells to build up too quickly. This can lead to thick, scaly patches that itch, crack, or feel sore. It can also affect the scalp and nails.
You cannot catch psoriasis by touching or hugging someone who has it. According to the American Academy of Dermatology (AAD), psoriasis is not contagious.
What can trigger a flare?
Triggers vary from person to person, but common ones include:
• Stress
• Skin injuries, including cuts, scratches, and sunburn
• Infections, such as strep throat
• Cold, dry weather
• Smoking and heavy alcohol use
• Certain medications—talk with your prescriber before making changes.
What treatments can help?
According to the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), treatment depends on the type, severity, and location of psoriasis. Options include:
• Prescription creams and ointments, including corticosteroids and vitamin D-based medicines
• Medically supervised light therapy (phototherapy)
• Oral or injectable medications, including biologics that target specific parts of the immune system
There is no cure yet, but treatment can help control symptoms. Moisturizing and managing personal triggers can also help.
