The provided evidence confirms that Ebola is a severe disease and mentions a specific strain (Bundibugyo) for which no vaccine or treatment existed at the time of the Al Jazeera report. However, none of the provided sources specifically address the claim that a rare strain 'outran doctors' or spread faster than medical interventions could contain it. The evidence describes the nature of the virus and general outbreak updates, but does not provide a factual basis to confirm or deny the specific narrative of the virus 'outrunning' medical efforts.
