Ebola Virus Ribonucleic Acid Detection in Semen More Than Two Years After Resolution of Acute Ebola Virus Infection

Abstract

Among 149 men who survived Ebola virus disease (EVD) and donated semen 260-1016 days after EVD onset, Ebola virus (EBOV) ribonucleic acid (RNA) was detected in 13 (9%). Of 137 men who donated semen 2 years after EVD onset, 11 (8%) had an EBOV RNA-positive specimen. The mechanism underlying the persistence of EBOV RNA in semen is unclear, and it is unclear whether the detection of viral RNA represents the presence of infectious virus.
