Drs. Nancy and Jerry Jaax, the husband-and-wife veterinary team featured in Richard Preston's book "The Hot Zone" about the deadly Ebola virus, will speak from noon to 2 p.m. Wednesday, Nov. 1, at the University of California, Davis School of Veterinary Medicine. The Jaaxes, both colonels in the Army Veterinary Corps, will speak for one hour to veterinary students about career opportunities in the Army. The second hour will be open for questions and answers. The talk will be held in Room 170 Schalm Hall of the campus medical sciences complex. Jerry Jaax was the leader of the team of soldiers and scientists assigned to deal with the 1989 outbreak of the Ebola virus in a monkey facility in Reston, Virginia. Ebola virus, which destroys its victims' blood-clotting mechanisms, causing massive internal bleeding, is 90 percent fatal. The strain found in the Reston outbreak, however, killed only the infected monkeys but did not harm any of the humans involved. (Fred Murphy, now dean of the UC Davis School of Veterinary Medicine, also was active in the Reston ebola outbreak as the director of the federal Center for Infectious Diseases of the Centers for Disease Control. An authority on viruses, Murphy was the first to capture an image of the Ebola virus with an electronmicroscope.) Nancy Jaax continues to work at the U.S. Army Medical Research Institute of Infectious Diseases, a laboratory devoted to highly hazardous viruses, bacteria and toxins. Jerry Jaax was recently assigned to the headquarters of the U.S. Army Medical Research and Material Command.
