Key inclusion & exclusion criteria

- INCLUSION CRITERIA FOR EVD SURVIVORS

A volunteer of any age with a diagnosis of EVD within the past 2 years who is on the
Ministry of Health (MOH) Registry of EVD survivors is eligible to participate.

- Willingness to participate in examinations at one of the participating health
facilities

- Willingness to provide informed consent/assent

Individuals on the MOH Registry were PCR positive for EVD and treated at an Ebola Treatment
Unit (ETU), Community Care Center (CCC) or holding center. Periodically, participants
enrolled will be matched against the MOH Registry to verify that those enrolled are EVD
survivors. If a participant enrolled is not on the registry, their antibody levels at
baseline will be assessed. If antibody levels are present, the participant will continue to
be followed as an EVD survivor. If antibody levels are not present, the participants will
no longer be followed as an EVD survivor and may be withdrawn from the study. Participants
brought to the NIH Clinical Center will have documentation of positive Ebola virus PCR and
a clinical syndrome compatible with acute EVD.

EXCLUSION CRITERION FOR EVD SURVIVORS

Any condition in the judgment of the study staff that would make the volunteer unable to
participate in the study.
