Ebola virus disease surveillance in the absence of a confirmed case; the case of the rwenzori region of uganda

Abstract

Introduction: the August 2018 ebola outbreak in the Democratic Republic of Congo turns out to be second largest outbreak of ebola in public health history. The response to the outbreak which would have halted wider spread to neighboring countries failed. Hence, high risk districts in Uganda initiated preparedness activities in the wake of a possible inflow of cases. This study was therefore designed to identify, describe and assess surveillance activities and preparedness in the Kasese, Ntoroko and Bundibugyo districts of Uganda. Methods: the study employed the mixed method approach. The qualitative arm involved the use of participant observation to describe surveillance activities that were carried out as part of the ebola preparedness surveillance in the high-risk districts. The quantitative arm included assessment of 102 health facilities on ebola virus disease preparedness with a WHO standard checklist hosted on the Open Data Kit software. Descriptive statistics were performed using STATA (version 14). Results: the study showed that high risk districts employed numerous interlocking public health emergency activities which included readiness assessment, risk mapping and temperature-based screening for ebola at points of entry. Most health workers (91.18%) could correctly state the case definition of ebola although only 56.86% of them were trained on ebola surveillance. Conclusion: health worker knowledge on ebola virus disease case definition was high but training and logistics were inadequate. Continuous efforts are required to sustain health workers knowledge on ebola surveillance through trainings and supportive supervision whiles addressing gaps in the operation of ebola screening posts.
