Preliminary findings from the study presented in February 2016 indicate that both Ebola survivors and their close contacts have a high burden of illness. However, the prevalence of eye, musculoskeletal, and neurological complications was greater among the individuals who survived EVD. Thirty-eight percent of the 97 male survivors who provided one or more semen samples for analysis had Ebola detected in their semen at least once. In one case, Ebola was detected in participant’s semen sample 18 months after he had EVD symptoms. In a subset of 126 contacts who reported sexual activity with a survivor, only four percent reported regular condom use, raising concerns about potential sexual transmission of EVD. However, no cases of sexual transmission have been detected in this study thus far.
