The number of people dying from malaria in India has been hugely underestimated, according to new research.

The data, published in the Lancet, suggests there are 13 times more malaria deaths in India than the World Health Organization (WHO) estimates.

The authors conclude that more than 200,000 deaths per year are caused by malaria.

The WHO said the estimate produced by this study appears too high.
