New research from U-W Madison could help people with the Ebola virus learn whether they’ll die or not. Scientist Yoshihiro Kawaoka led a team that studied cases in Sierra Leone which had an outbreak of Ebola three years ago. The team looked at 29 blood samples from almost one dozen patients who survived the virus — and nine samples from those who didn’t. The virus was deactivated before the samples were shipped to Madison, where scientists created biomarkers that can help identify fatal infections from lesser cases. Kawaoka and Pacific Northwest National Lab biologist Katrina Waters both authored the study’s findings — and Waters called it the most thorough analysis of Ebola blood samples.
