Here is another article, maybe in a few days they will have more info. From the symptoms described in Promed, it doesn't sound to me like heatsroke, which is what they are guessing in this article.

From correspondents in Calcutta

AT least 15 children below the age of five have died and more than 100 have been taken ill in a "mysterious disease" outbreak in India.
The Director of West Bengal health services, Prabhakar Chatterjee, said the disease had affected more than 100 children below the age of five in three villages - Kuchina, Kaddamtala and Natundiya - in Murshidabad district, about 320kms north of state capital Calcutta.
"We are yet to get the details. At least 15 children have so far died during the past five days," he said.
"Over 100 are admitted to the local health centre.
"The disease might have been caused by the excessive heat sweeping the district for over a fortnight."
Chatterjee said a special medical team had already been sent to the district and another would be sent tomorrow to find out the cause of the illness.
"Blood samples of the affected children have been taken and sent to the laboratory for tests.
"We hope the nature of the disease might be known in a day or two."
A heatwave has swept most of India in the past fortnight, killing nearly 1350 people.
About 90 per cent of the deaths have taken place in southern Andhra Pradesh state.
Thanks for the info...something to watch.
