a bundibugyo-strain ebola outbreak in eastern democratic republic of congo has reached roughly 515-600 confirmed cases with around 91 deaths, and has now crossed into uganda with 19 confirmed cases and 2 deaths, indicating sustained cross-border transmission. burial teams and healthcare workers are reportedly being attacked in zones under islamic state influence, and a published study estimates true case counts may exceed double the official figures. an outbreak spreading across a national border through an active conflict zone where responders are being targeted is structurally hard to contain.
