No amount of "switching off", though, spares the MSF staff from the wider scale of the fatalities around them. The clinic, one of three now operating in Monrovia, has seen 350 deaths in the last month alone. Since all infected bodies have to be burned, the casualties have exceeded the ability of Monrovia's local crematorium to cope. MSF has had to import an incinerator from Europe - normally used for livestock - to assist. For an aid agency that prides itself on triumphing in even the most difficult operating circumstances, it is a depressing reminder of how far there is to go.
