Cassia poisoning behind mysterious disease in children in Uttarakhand.

I would like to compliment ‘Indian Pediatrics’ for publishing and providing a solution to the recurrent annual outbreaks of a mysterious fatal disease affecting young children of western UP and Uttarakhand for last many years(1). This illness often labeled as ‘acute viral encephalitis’by the investigating agencies and ‘brain fever’ by lay media has been puzzling pediatricians and public health experts for over a decade.
