The ongoing Ebola virus disease epidemic (August 2018─October 2019) in the Democratic Republic of the Congo, has been exacerbated by deliberate attacks on healthcare workers despite vaccination efforts. Using a mathematical/statistical modelling framework, we present the quantified effective reproduction number ( at national and regional levels as at 29 September. The weekly trend in displays fluctuations while our recent national-level falls slightly above 1.0 with substantial uncertainty, which suggests improvements in epidemic control.
