The term loose cannon perhaps describes him best. And the sight of him would have been funny, had his way of earning a living not been so deadly for his victims or ‘patients’. He is the bulla (wandering) doctor. His name is Yudhishtra and we met him at Gangabada village which he crosses en route to his destination— the remote hamlets of Gangabada panchayat. One day, 10 years ago, he invested in a few syringes, bottles of glucose and chloroquine and set out from his home in Mandasa (Andhra Pradesh) to scour the hills of Raigada, Orissa, in search of "patients".
