Remember that big Ebola outbreak in 2014? The biggest outbreak of the virus ever?

Well, Ebola is back and this time it might be even harder to fight. Julia Ballouz has

been covering the story for Vox.

In August, the DRC has been battling what's now the world's second largest Ebola outbreak

in history. Nearly 700 people have been infected and more than 430 have died. This is a really

big outbreak.

Where do things stand as of right now?

Ebola spread into 12 health districts in the country, which is the regions by which they

break up their health system and that just means it's really geographically dispersed.

But the good news is it hasn't yet hit any major cities. You know when Ebola starts to

spread into city, the response becomes really complicated and difficult and it's not there

yet. But last week there was four cases confirmed in a place called Kanya, which is halfway

between one hotspot of the outbreak and a major DRC city called Goma with a million people.

The worry that the WHO expressed to me last week is that the outbreak appeared to be heading

toward Goma this major city. And if that happens then it becomes a much more serious situation

and potentially what's called a global public health emergency, which means it's a really

grave situation.

And I'm quite concerned that it hasn't risen to a higher level of attention because as we

know these viruses don't pay attention to borders and they move very quickly, it could

kill a whole lot more people.

So what's being done to prevent the spread of this?

Responders finally have an effective Ebola vaccine, it's still an experimental vaccine,
