Do infections cause vasculitis?

ANSWER

Vasculitis can sometimes develop after an infection has come and gone. Usually in these cases, the infection triggers an abnormal response in the person's immune system, damaging the blood vessels. Vasculitis also may be related to other diseases of the immune system that the person has had for months or years. For example, it could be a complication of rheumatoid arthritis, lupus, or Sjögren's syndrome.
