On Thursday, the World Health Organization (WHO) said its advisory groups had identified some potential therapies and vaccines to test for Ebola, but recommended they be used exclusively in clinical trials to ensure they are safe and effective. Each would require months of development.

The Bundibugyo virus causing the outbreak in Congo suspected of killing more than 200 people is less common than others that cause Ebola disease, which is complicating the response because there are no specific treatments or vaccines.
