An international effort is underway to contain an Ebola outbreak in the Democratic Republic of Congo and Uganda that has already led to dozens of suspected deaths, with the United States looks to relocate a “small number” of citizens affected.

US health officials are supporting DRC and Uganda after a deadly Ebola outbreak triggered regional and global response efforts.

At least 80 people have died in what the World Health Organization says potentially could be a "much larger outbreak than what is currently being detected and reported".

The World Health Organization declared the outbreak a public health emergency of international concern on Saturday.
