I'm not but I speak to people who are and I have worked on 3rd world development projects. You don't need to be a health care expert to understand the mathematics of viruses. The maths isn't that complex ( described as the R factor eg. an R of 2 will spread a sick person's virus to 2 others.) Ebola is however a moving and (slowly) evolving virus and its R factor will vary considerably depending on the environment (meaning population density, sanitation standards, physical climate, culture etc) . The so called "R" factor for developed countries will be very low meaning ebola wont spread effectively in Australia.
One significant factor thing commentator's haven't commented on is transfer of the mutated form back from humans into higher primates and animals, and most importantly fruit bats. This can lead to further virus mutation.
