Tedros Adhanom Ghebreyesus warns of ‘catastrophic collision of disease and conflict’, as Uganda closes border with DRC The head of the World Health Organization has called for an immediate ceasefire in the eastern Democratic Republic of the Congo to help tackle the Ebola outbreak there, as Uganda closed its border with its neighbour in an effort to stop the spread. Tedros Adhanom Ghebreyesus posted on social media that the region was in the midst of a “catastrophic collision of disease and conflict with the Ebola outbreak in Ituri province outpacing the response”. Tedros said on Monday that he would travel to the DRC this week.
