It is estimated that approximately 1.3 million people in the United States and approximately 1% of the global population have rheumatoid arthritis (RA). The exact number of people affected by RA worldwide is difficult to determine due to differences in definitions, diagnosis, and access to healthcare. However, it is estimated that RA affects approximately 1 in every 100 people worldwide. RA is a chronic autoimmune disorder that causes inflammation and damage to the joints, as well as other organs in the body. The exact cause of RA is not known, but a combination of genetic, environmental, and lifestyle factors is thought to contribute to the development of the disease.
