Ebola Zaire strain mutation?

[steve tichy]

     According to my local paper on May 15th, they had stated Ebola
Zaire in 1976 took about seven days to incubate, but the current Kikwit
strain is only taking four days to incubate and it is killing its
victims faster.
     Has anyone heard whether the Ebola Zaire strain has mutated or
not?  Or, is it my local papers interpretation?


Thanks,
