Dr. Ivan Jacobs appears in The Pathos in the Pathogens. A representative of the Centre of Disease Control, he assisted the team in the investigation of a rapidly-decaying corpse that he was concerned may signify the start of a potential epidemic. Although their investigation confirmed that the disease that had killed the victim could only be contracted through direct blood transmission, Jacobs continued to assist them after Arastoo Vaziri was infected with the same virus, offering his insight into identifying and treating the disease until they could force the diseases' creator to give them the cure.
