Is my vasculitis contagious?

Vasculitis. Vasculitis is an inflammation of the blood vessels and both arteries and the veins can be affected. The inflammation is caused by a type of white blood cell that sticks to the blood vessel, creating a cascade of inflammation (and destruction). There are many types of vasculitis: only some have been linked to an initial infectious component (kawasaki's) but none have been found to be catchy.
No. Some forms of vasculitis follow an infection but vasculitis itself is characterized by inflammation rather than active infection. None of the vasculitides are contagious.
