The United Nations World Health Organization (WHO) confirmed a second case of Ebola in a new outbreak in the Democratic Republic of Congo, and officials are trying to trace 125 people who may have been exposed.

There are now 19 confirmed and suspected cases of Ebola identified in the remote northeastern province of Bas-Uele province in northeastern DR Congo near the border with Central African Republic.  Three people have died, including the man believed to be the first person infection in this outbreak.  Officials aren't sure how he picked up the often lethal virus.

This comes a year after the end of the West African Ebola Epidemic that killed more than 11,300 people mostly in Guinea, Sierra Leone, and Liberia.  Congo has had Ebola outbreaks before, but in those episodes the virus' spread has been limited by the dense forest. 

The global vaccine alliance Gavi says that 300,000 of Ebola vaccine developed by Merck could be available in case of a large-scale outbreak and that it stood ready to support the Congo government on the matter.
