If we can find the bodies of these Americans that will be good, but the priority needs to be to "sanitize" these areas so that rotting corpses do not spread more disease.

Decaying corpses have nothing to do with spreading disease after a disaster.

There is danger that diseases may spread throughout Haiti if the corpses that litter its streets will not be collected for proper disposition, international aid groups told CNN today.

And while there is not great risk, there is still a risk that disease can be spread from the corpses especially in an area where there was and is a high incidence of infection among the native population.

No, it’s the rodents and other animals that come in to eat them that spread diseases.

It is urgent to bury the dead, and if it can be done no other way, it has to be done with bulldozers and mass graves.
