American-itis 

American-itis, also known as the American Plague, is a rather serious illness caused by overusing an american accent and resulting in you being unable to stop using an american accent. It can vary in severeness, ranging from only a few words being only spoken in an american accent to your entire vocabulary being saboutaged by the accent. Treatment is unique for each patient, and the illness can vary lasting from just a few days to a whole lifetime.
