Cyclone Nargis hit Myanmar on May 3 devastating large parts of the country with over 27,000 people still unaccounted for.
The UN under-secretary for humanitarian affairs and emergency relief, John Holmes, however, said up to 2 million people have been 'severely' affected and put the death toll at "between 63,000 and 100,000, or possibly even higher."
A state of emergency has been introduced in the five worst-hit areas - the Irrawaddy delta, the cities of Yangon and Pegu, and the states of Karen and Mon. Most of the deaths have been in the low-lying Irrawaddy delta region.
The UN, governments and international relief agencies said aid has begun to trickle through to the disaster-hit country, but many organizations have reported that distribution is being delayed by the military authorities, who are reluctant to permit foreigners into the worst-hit areas.
British aid group, Oxfam said the death toll could hit 1.5 million if disease broke out and people did not get access to clean water.
The situation in the disaster-stricken country is extremely dangerous and the risk of epidemic is very high due to unsanitary conditions caused by rotting carcasses and corpses across the region.
