Patna: It is official now, the acute encephalitis syndrome (AES) that has killed 233 children in Bihar since May is not Japanese encephalitis, announced Thursday.
The ruling has come from the Pune-based National Institute of Virology (NIV).
"In fact the disease remains a mysterious one," Additional Secretary (Health) R.P. Ojha said.
"NIV has told the Bihar government that no one had a positive strain for Japanese encephalitis," he said.
According to him, the NIV collected cerebral spinal fluid and blood samples of 73 patients from Muzaffarpur district.
