There are no vaccines or treatments for the strain of Ebola that has killed more than 200 people in DR Congo and Uganda, but several are being urgently developed in the hope of reining in the outbreak.

More than 875 cases of the Bundibugyo strain have been confirmed, including 202 deaths, in a little over a month, the African Union's health agency said on Thursday.

However the true scale of the outbreak remains unknown, humanitarian organisations have warned, because the virus could still be spreading in remote, poor and conflict-wracked areas of the Democratic Republic of Congo.

To help address the crisis, scientists, pharmaceutical companies and funding bodies have been racing to develop new vaccines and treatments that can be swiftly and safely tested in humans.
