Patients will be recruited in the Ebola Treatment centre managed by Medecins Sans Frontieres (MSF) in Conakry. All patients and/or relatives presenting at the centre will be informed about the study, and will be invited to provide consent at the time of admission inside the treatment centre. Only patients for whom ebola infection is confirmed via polymerase chain reaction (PCR) will be enrolled in the study. After inclusion, eligibility to the intervention will be assessed at the time of enrollment (when the patient is moved to the area for patients with confirmed Ebola) and will be reassessed on regular intervals as long as the patient did not receive plasma transfusion. The re-assessment of eligibility to receive CP happens at 8h and at 12h, and is repeated until 48 hours after inclusion. If the eligibility criteria are not met by 48 hours after inclusion, only SC will be continued.
