well, it's difficult to decide when it's under control or not. As I said in my message, there is no reason to panic at all, just to be careful and indeed try to get some information.
Thw whole thing about Marburg is, that it usually starts in remote areas - and, since people die pretty quickly and the means of transport are very limited, usually it can be contained relatively easy - but this case seems to continue moving slowly northbound.
Although I get indeed my information from the field via UN-agencies and NGO's here, sometimes the BBC can be more reliable - communication here is never the strongest point... but we also know that sometimes news is based on only a few quotes from one or another guy...
So, all this actually just to say: don't let it stop you from doing what you planned to do, but just keep your eyes and ears open for updates, and use your best judgement...
