The same might be said of humans. Since we share a common susceptibility to the virus, I believe it's of dire concern. In particular since the spread to the ape population seems to indicate that the virus is continuing to spread, and it's lethality is not decreasing as it mutates.
There is no doubt Ebola is a threat to humans, however humans have access to things Primates do not, #1, it appears at present that survival rates from Ebola have been rising in latest outbreaks, at one point it was believe upwards of 80% exposed die, now more accurate studies and analsys show that number to be closer to 50%. We also have been blessed with things by our creator that Apes have not, which has lead us to develop things like hospitals and scientific knowlege that will eventually and continually improve treatement for this disease.
Ebola is scary as it has a high mortality, and rapid death after exposure.. however Humans also know when an outbreak is occurring and behave approriately. It is not likely that Ebola will turn into a world wide outbreak in the modern age. Humanity has always managed to survive epidemics, by shifting our behaviors in accordance to them.
HIV is a far greater threat today in terms of numbers than Ebola is or likely will be, but it kills more slowly, and is almost completely a behavior driven disease. Would a major Ebola outbreak be a good thing? Of course not. However I don't see it as a major threat to humanities further existence on the planet.
At one time Smallpox was an easily transmittable, rapidly killing disease that horrified the world. However, humans largely adapted behaviors to keep the disease from every being a threat to the existence of the species, and over time developed treaments and immunizations for the very disease itself, as early as the 1700s if I am not mistake (perhaps even earlier) intentionally infecting oneself with Cow Pox was know to protect one for life from Small Pox in Europe and the new world.
Today the disease has been completely irradicated from the planet, and short of an accidental exposure in the lab or an intentional exposure by a terrorist group poses no real threat to human populations.
