Is rheumatoid arthritis contagious

No rheumatoid arthritis is not contagious. There does seem to be a genetic connection meaning that if any of your parents have it you are also more likely to suffer from it. However you would for example not get Rheumatoid artritis if you were to receive a blood donation from someone with RA. RA is a chronic Autoimmune disease where for reasons not yet understood the immune system turns on selected tissues of the body leading to their destruction.
