This article says that Rift Valley fever and the Ebola virus are linked to shifts from dry to above-average rainfall. It seems to me that Africa has a tremendous number of hibernating animals. They explode out of the ground when it rains. They and the animals that feed on them would be handled and eaten by humans in the area. Why not suggest to researchers that they dig up some of these creatures and examine them. One of those could be the vector they’re looking for.
