Clinical health outcomes of Ebola virus disease survivors eight years post recovery: a cross-sectional study in Sierra Leone

Abstract

AbstractBackgroundThe West African Ebola virus disease (EVD) epidemic that occurred between 2013-2016 resulted in >28,000 confirmed cases and >11,000 fatalities. Thousands of survivors necessitate an understanding of the long-term health effects and future medical needs of these patients.MethodsA cross-sectional study of 595 EVD survivors from Sierra Leone and 403 close contacts (n=998). An in-person survey conducted between November 2021 and March 2022 included demographics, clinical health symptomology assessment of each organ system and a reproductive health assessment including sexual dysfunction question sets. The frequency of each disorder was examined and the association of each disorder with EVD survival was assessed.ResultsOf 12 number of symptom types, five were reported by >50% of EVD survivors (Ocular, Neurological, Constitutional, Genitourinary, Dermatological), and all but one were reported by >40% of EVD survivors. Symptom types associated with EVD survival included ENT symptoms (AOR: 8.75, 95% CI: 5.63 – 13.60, p < 0.001), ocular symptoms (AOR: 7.18, 95% CI: 5.02 – 10.25, p < 0.001), dermatological symptoms (AOR: 4.16, 95% CI: 3.06 – 5.65, p < 0.001) and cardiovascular symptoms (AOR: 2.96, 95% CI: 2.12 – 4.13, p < 0.001).ConclusionThe West Africa EVD epidemic resulted in a high prevalence of persistent health issues among disease survivors. Continued support for survivor services in West Africa is crucial, and future outbreak response planning should include dedicated funding to ensure adequate care for survivors, both during the acute phase of infection and throughout the post recovery period.
