Sudden Onset Autism, or S.O.A for short, is an extremely rare condition of unknown origin. Development of this disease is both abrupt and severe. As of now, the pathogenesis and mode of infection have eluded even the most qualified of research teams at Harvard, Hopkins, and Yale. Some have suspected that transmission occurs through contact with an infected person, especially prandially. There is still hope for a cure, although we may be decades away.
