Here's the thing about the spread of new diseases: you start with a load of people getting sick and it gets put down to some other illness. Eventually a trend forms that points to a new illness. Now, at that point, you have no idea how many people have it because it's probably asymptomatic in most cases and you can only identify the ones that get sick. Because you're now aware of it, and looking for it, you start identifying lots of sick people with it, and so the number of cases skyrockets. And because you're now identifying it in people who were previously already very ill, the % of confirmed cases that die also skyrockets. This is the point where the media sensationalise it because the stats look so awful (but remember, it could be the case that 90% of your population have it but it only has symptoms in very few). Then people in areas of outbreaks take basic measures like hygiene, quarantine, and such, and we get a better look at where the disease stems from. You then reach a point where the death toll remains pretty constant but the number of new cases decreases. This again looks awful because it looks at face value highly lethal, but really you've reached the point that the disease is dying out. That's pretty much where we're at.
The time to worry is when the number of new cases starts accelerating and exceeding the death count because that's the way that it can spread wider and wider. In order for a disease to maintain itself it needs to spread faster than people are diagnosed, otherwise it kills all its hosts before it can spread sufficiently to survive itself.
I've probably explained that badly and made some basic errors because I don't have a background in infectious diseases, but the point is that it's taking a very predictable trend that indicates absolutely nothing like a global epidemic. The media makes it a craze, governments have to be seen to do something and so start all the quarantining and such, but this will go the way of SARS, swine flu, avian flu, Spanish flu, that were all going to cause mayhem across the globe.
