One of the film’s biggest issues is the lack of clarity regarding the period it is set in. The film neither explicitly states its era nor convincingly portrays one. You are just left to hazard a guess based on some costuming and prop choices, particularly for the character and his cohorts.
The film is based on Nigerian medical doctor Ameyo Adadevoh who was credited with having curbed a wider spread of the Ebola virus in Nigeria by placing the patient zero, Patrick Sawyer.
