• There was not enough water on hand to get the fire under control;
• The hydrant system did not work well because much of the equipment was not standardized;

• A local equine epidemic had struck the city fire department’s horses making it difficult to get the fire engines to the correct locations at the right times.
• Explosions were used to attempt fire breaks, but this high-risk strategy was not executed with enough precision and served only to further spread the fire.

aire ebolavirus, Bundibugyo ebolavirus, and Sudan ebolavirus are the three species of Ebola virus responsible for the larger outbreaks in Africa. Zaire ebolavirus, the most fatal Ebola virus, was associated with the 2014-2016 outbreak in West Africa, the largest Ebola outbreak to date with more than 28,600 cases. Other large outbreaks of Zaire ebolavirus have resulted in hundreds of cases in the Democratic Republic of the Congo (DRC) and Gabon. Smaller outbreaks of this species have also occurred in DRC and Gabon, as well as the Republic of the Congo and South Africa. Sudan ebolavirus, with a fatality rate of 50 percent, has been the cause of several outbreaks in Uganda and others near the border between South Sudan and DRC. Bundibugyo ebolavirus, discovered in 2007, was associated with two outbreaks, one in DRC and the other on the border of DRC and Uganda. Taï Forest ebolavirus, the only other Ebola virus found in West Africa to date, was the cause of one case identified in Côte d’Ivoire.
