Bundibugyo strain first identified (2007)
An outbreak of haemorrhagic fever in Uganda's Bundibugyo district turned out to be a previously unknown species of Ebola. The strain killed 37 of 149 cases — a 25% fatality rate, lower than the Zaire strain but still severe. Ugandan and US CDC scientists characterized the new species and named it after the district.
Uganda contained the outbreak in three months using contact tracing and isolation. No vaccine existed for any Ebola strain at the time.
Bundibugyo joined the four other known Ebola species but received minimal vaccine development attention, because Zaire strain caused most outbreaks and most deaths.
The 2007 response is the template Uganda is using now. The vaccine gap that existed then still exists for this strain.
