Ebola exposure risk

From ANIMAL PEOPLE, March 2004:

FORT DETRICK, Maryland– A National Research Council fellow
doing postdoctoral virology research at the U.S. Army Research
Institute for Infectious Diseases accidentally grazed herself with a
needle on February 11 while injecting mice with a weakened strain of
Ebola virus. Quarantined for 30 days on February 12, at “Level
Four” biosecurity, she remained free of Ebola symptoms at least
through February 18, reported David Dishneau of the Baltimore Sun.
The researcher was trying to develop a vaccine for Ebola. Ebola
victims typically die after several days of high fever, diarrhea,
vomiting, and both internal and external bleeding.
