Researchers in the University of Liverpool used studied blood samples taken from recovering patients during the 2013 West Africa Outbreak. They wanted to study gene products to align them as predictors for patient outcomes. The results were promising and could be utilized in future Ebola investigations. The blood samples were pooled into two categories those that died from acute infection and those that recovered and were free from Ebola. The analysis showed that the host immune response did not act as a predictor for the outcomes of the patients. The greatest predictor was still in accordance with past knowledge that the viral load of the virus was the greatest predictor of the whether the patients developed severe cases or recovered.
