Medical personnel are working to contain a new Ebola outbreak in the eastern Democratic Republic of Congo, where an American missionary is among those who have tested positive for the disease. The rapid spread of this outbreak has alarmed health experts. The World Health Organization has declared it a public health emergency of international concern due to the high risk of the disease spreading beyond the DRC's borders, after two cases were confirmed in Kampala, the capital of neighboring Uganda. There have been 105 suspected Ebola deaths and 393 suspected Ebola cases across nine health zones in Ituri province, with eight cases confirmed by laboratory testing, according to the Congo Health Cluster.
