Event description
The Bundibugyo virus disease (BVD) outbreak in the Democratic Republic of the Congo continues to expand rapidly, with sustained transmission, persistently high mortality, and ongoing geographic spread. It is now the largest BVD outbreak ever recorded and the second largest Ebola disease outbreak in history after the 2013 – 2016 West Africa epidemic. Since its detection only a few months ago, the epidemic has grown at an exceptional rate, highlighting its intensity and the challenges facing response efforts. Although no new international spread has been detected, continued transmission indicates that the outbreak remains in an expansion phase and continues to pose a high risk of regional and international spread.
