Psoriatic Arthritis Awareness Day, observed worldwide every September 28, aims to educate the public about psoriatic arthritis, a chronic inflammatory disease affecting nearly one-third of psoriasis patients. Launched in 2016 by Celgene Corporation and the National Psoriasis Foundation, the day highlights the importance of recognizing, diagnosing, and treating this condition. Psoriatic arthritis can develop in individuals with any severity of psoriasis, typically manifesting about a decade after skin symptoms appear. Participants are encouraged to educate themselves about psoriatic arthritis, share personal experiences, make donations to relevant organizations, and promote awareness on social media using specific hashtags. The day serves as a reminder of the significant health risks associated with psoriasis and the impact of psoriatic arthritis on quality of life.
