Duration of Ebola virus RNA persistence in semen of survivors : population-level estimates and projections

Ebola virus can persist in semen after recovery, potentially for months, which may impact the duration of enhanced surveillance required after interruption of transmission. This article refers to a combined recent data on viral RNA persistence with weekly disease incidence to estimate the current number of semen-positive men in affected West African countries. The study found the number to be low, and since few reported sexual transmission events have occurred, the future risk is also likely low, although sexual health promotion remains critical.
