Govt has formulated national policy for rare diseases: Nadda

A newsletter published by the "Indian Organisation of Rare diseases" was also released on the occasion.

Noting that it was an irony that the "rare diseases" were rarely discussed, Singh pointed out that the reason for this was that the healthcare system of the country was preoccupied with more prevalent diseases, while these "rare diseases", usually genetic or existing from the birth, had a prevalence of hardly about seven per cent.

He said most of the literature available on these diseases was written by Western authors.

Even the definition was based on Western inferences, like in the USA, a disease was said to be "rare" if it affected less than two lakh people, while in Europe, it was categorised as a "rare" disease if it affected not more than five persons per 10,000 people, Singh said.

"Therefore, there is a dire need of compiling the Indian data for these diseases, based on the epidemiological, phenotype and other factors peculiar to India," he added.

Singh said in the larger perspective, some of the diseases, which were rare in India till about three decades ago, had suddenly become widely prevalent throughout the country.
