There is that whole hygiene and monkey meat (Bush meat) thing. They still haven't much recovered from the civil wars.
That 'bushmeat' also includes the migratory fruit bats (considered a delicacy) also thought to be a reservoir for the disease, and the reason the outbreaks are sporadic, varied in location without other clear patterns, and were associated with caves, mine shafts, etc.
The latest patient zero was believed to be a toddler who may have picked up some fruit contaminated with guano, and typical of toddlers, saw food and started eating...Over 10,000 dead, and another nearly that many who survived through herculean international agency efforts to combat the disease, many of whom were health care professionals or volunteers (imho the real heroes of the epidemic).
But in hard times, and even in good, 'bushmeat' has a following, and is even sold in the US in places.

The civil wars were devastating, add in the epidemic, and the likes of Boko Haram, and the region is having a hell of a go.
