The company immediately set up a quarantine area of its hospital for the infected woman, who soon died. 

They distributed hazmat suits to workers. They researched everything they could, built a treatment center, and set up a comprehensive response. Transmission stopped. Even now, the only cases seen in this area come from outside the community.

even as the worst Ebola outbreak ever recorded rages all around them, Firestone appears to have blocked the virus from spreading inside its territory…. A key reason for Firestone's success is the close monitoring of people who have potentially been exposed to the virus — and the moving of anyone who has had contact with an Ebola patient into voluntary quarantine. By most accounts, this Ebola outbreak remains out of control, with health care workers across West Africa struggling to contain it.
