Criteria for the qualification of Ebola virus persistence–derived transmission event*

Criteria no. Explanation

2 Absence of known exposure of the presumed recipient (or index person) to a person with Ebola virus disease in the 21 days before infection
No evidence of ongoing transmission in the community where case or cluster was recognized

*Criteria apply to recipient or >1 person in the cluster (if the index person is not the recipient).
