Viral encephalitis has killed hundreds of children in Uttar Pradesh over the last decade

More than 400 people, mainly children, have died in an outbreak of viral encephalitis in northern India, health officials say.

So far 2,300 patients have been admitted to a hospital in the affected Gorakhpur area of Uttar Pradesh state.

A doctor told the BBC that it was a "tragedy beyond imagination", with children dying every day.

Nearly 6,000 children have died of encephalitis in the hospital since the first case was detected in 1978.

Most of the deaths this year have happened since July, doctors say.

The disease occurs regularly during the monsoon in the Gorakhpur region bordering Nepal in the foothills of the Himalayas.

The low-lying areas are prone to floods, providing a breeding ground for mosquitoes which commonly transmit the virus.

'Tragedy'

Doctors say affected patients come from 10-12 districts in the region, and are mostly poor.

Until 2005, the majority of deaths were caused by Japanese encephalitis, caused by a mosquito-borne virus, doctors say.

"It is an unbelievable tragedy - children are dying every dayâ€
