A “toxin” in litchi fruit could be
the reason for mysterious deaths of children in Bihar and neighbouring
districts since 1995, the US researchers have claimed. “An ongoing 2014
investigation has found no evidence of any infectious etiology and supports the
possibility that exposure to a toxin might be the cause,” the report published
by the Centres for Disease Control and Prevention (CDC), Atlanta, said. While,
outbreaks of an unexplained acute neurologic illness affecting young children
and associated with high case-fatality rates have been reported in Muzaffarpur
district of Bihar since 1995. There have been multiple epidemiologic and
laboratory investigations of this syndrome, leading to a wide spectrum of
proposed causes for the illness, including “infectious encephalitis” and
“exposure to pesticides”.
