Blood tests show a gravely ill Congolese woman, who doctors feared was suffering from the Ebola virus, does not have a contagious hemorrhagic fever in the same class, health officials said Friday.
The woman, hospitalized Sunday after traveling to Canada, was in critical condition on life support Friday. Doctors do not know what she is suffering from, but said people who had contact with her will not contract it.
"We do not have a best guess at this point," Dr. Mark Loeb said. "We might or might not come up with a specific diagnosis. We don't think there's anything that's transmissible that would be life-threatening."
Scientists ruled out the Ebola virus on Wednesday. Loeb spoke after his hospital here received test results from a Canadian laboratory and the U.S. Centers for Disease Control and Prevention in Atlanta.
A nationwide Canadian contingency plan to contain a group of diseases known as viral hemorrhagic fevers was called off, and hospital staff treating the woman will no longer have to wear extra protective gear, such as sealed plastic suits.
