Chief of the Special Pathogens Branch of the CDC, McCormick has a great deal of personal enmity towards C. J. Peters, and believes that the CDC, not USAMRIID (a branch of the army), should take control of the Reston Primate Quarantine Unit after Ebola is discovered there. When Ebola ravaged Sudan in 1979, McCormick was on the scene and worked tirelessly both to research the disease and aid his dying patients. After sticking himself with a contaminated needle, he believed that he, too, would soon die of Ebola, and decided to spend his last days helping the sick. He did not fall ill, however, because the needle was actually contaminated with malaria, not Ebola. As a result, he does not believe that Ebola can be easily transmitted.
