High seroreactivities to orthoebolaviruses in rural Cameroon: a case-control study on non-human primate bites and a cross-sectional survey in rural population.

The detection of high level of seroreactivities against orthoebolaviruses in rural Cameroon where no outbreaks have been reported, raises the possibilities of silent circulation of orthoebolavirus, or of other not yet documented filoviruses, in these forested regions.
