I think it's compromised by the insecurity. As I mentioned, this is the first time that Ebola has hit a conflict-affected area. I believe there have been 10 outbreaks in Congo since the identification of the disease in 1976. This is the first time in an active conflict zone.
There was an Ebola outbreak earlier this year in the far west, in Equateur province, and then, I think within a week or two of it being declared over, we saw one emerge in this conflict zone.
Beni is the territory in North Kivu province affected by Ebola currently and beset by a number of armed groups, notably the ADF, which is a Ugandan group that has been there since the 1990s and which became very active in 2014. It has stepped up its violent operations since the Ebola outbreak. It was hoped that they would not be getting in the way of any kind of Ebola response, but the opposite has happened. They seem to be more and more active since the declaration of the epidemic.
It's very difficult to stop people from moving. A lot of people in the area rely on trade, notably with Uganda, for their livelihoods, so you have regular commerce people moving with goods every day. As much as you can regulate some of these movements, there are always ways around them. I remember working earlier this year in the northeast of the Congo bordering Uganda, and there was the official border crossing and 10 unofficial border crossings, essentially just paths through the forest.
