Dozens have died in a new Ebola outbreak in the Democratic Republic of Congo's Ituri province, with cases likely spreading weeks before the official announcement.

The highly contagious Bundibugyo strain, which has no vaccine, has already reached the capital, Kinshasa, and neighboring Uganda.

Limited testing suggests the true scale of the outbreak may be far larger, with experts warning conflict, displacement and poor access are making containment increasingly difficult.
