State Myanmar radio and television, the main official sources for casualties, reported a death toll of 22,980 with 42,119 missing and 1,383 injured in Asia's most devastating cyclone since a 1991 storm in Bangladesh that killed 143,000.

A U.S. diplomat in Myanmar said diplomats were hearing there could have been more than 100,000 deaths.

Aid officials say hundreds of thousands will have been left homeless in the vast swamplands of the delta, where mosquito-borne diseases such as malaria and dengue are endemic.

There will also be the risk of cholera and chronic diarrhea from filthy water and corpses rotting in the tropical heat and humidity of Southeast Asia.
