Like his wife Nancy Jaax, Jerry is devoted to his family, but does not hesitate to risk his life during the USAMRIID operation to contain the Ebola virus within the Reston Primate Quarantine Unit. Although he doesn’t feel comfortable with his wife handling Ebola during research at USAMRIID, Jerry himself ends up leading the team that must enter the contaminated building and euthanize hundreds of infected monkeys. At every turn Jerry is courageous but cautious, consistently putting the needs of his soldiers above his own.
