The UN World Health Organization (WHO) is warning of a "very high" chance of the deadly Ebola virus jumping outside the DR Congo's border into its neighbors.

DR Congo already had an Ebola outbreak earlier in the year which killed 33 people in the northwest.  The current outbreak in the northeast, apparently unconnected, is worse.  Health officials logged 124 confirmed infections, including 71 deaths.  Now, two more cases were discovered further afield, near the border with Uganda.

This part of the country has a highly mobile population and a rebel threat that has left health workers operating in a war zone.  They're also combating various rumors and fears about the disease, which spreads via the body fluids of those infected, including the dead.  Patients have gotten out of quarantined health facilities to seek "alternative care", spreading the virus in the process. 

The virus made it to the area near the Uganda border after a woman who had participated in burials of Ebola victims refused a vaccination and disappeared.  She turned up at a hospital near the border where she died.  The second death was her partner.

Meanwhile, the fighting has uprooted some 13,000 people, many of whom sought shelter across the Uganda border.  That country has had five outbreaks since 2000, and is preparing to begin vaccinations with the same experimental medicine being used in the DR Congo as needed.
