Bodies are already being left on the street.
Flies will land on these bodies, pick up the virus, and then land elsewhere. Other insects, rodents, etc., have the same potential.
I have yet to see a discussion of flies as a vector for Ebola. If they can spread the virus, as seems highly likely, then controlling Ebola in these regions is impossible.
If so, and violence ensues among the 'healthy', more cases are virtually guaranteed.
Things are not going well from what we can see.
