Washington: The World Health Organisation (WHO) has said it is trying to ascertain the exact number of Severe Acute Respiratory Syndrome (SARS) cases in India in the backdrop of Indian government's reporting only one case to the WHO.

WHO spokesman Dick Thompson said officially, the Indian government has reported one case to WHO, whose officials in India are, however, "trying to clarify what the situation is".

Dr Dele Davies, a Professor and Chairman of Paediatrics and Human Development at the University of Michigan, told the media, "It is hard to know if it is truly one case in India or whether it is a failure to recognise the disease or failing to report it. We are not really sure how good the surveillance is in these countries."
