Abstract

There are few effective communication interventions to respond to Ebola Virus Disease (EVD) outbreaks, and their development is a continuing challenge. The largest outbreak of EVD was first recognized in 2014 and once again highlighted the need for health education communication campaigns. EVD emergence and transmission are associated with behaviors that increase exposure to infected individuals and infected wildlife. In 2008–2009, an educational video-centered intervention consisting of a film followed by a structured discussion was developed to improve EVD knowledge, attitudes, and behaviors (KABs) for prevention of EVD and care of infected people. The film was produced for a Congolese audience in local languages and features doctors and residents from the region. The objective of the study was to assess the effectiveness of this intervention to change KABs related to EVD. The intervention was conducted over 12 months and reached >60,000 people; 220 individuals were sampled before and immediately after the intervention, and a subsample of 53 who had received the intervention 1 year earlier were interviewed to assess changes in KABs related to EVD. Statistically significant improvements in EVD recognition, transmission, and mitigation of risk after the intervention were observed. This study also demonstrates significant retention of knowledge one year after the intervention. Overall, the intervention was effective in improving KABs among a limited literacy population and knowledge was retained for more than one year. The materials and approaches developed were used in 2014 as part of a social mobilization strategy in response to an Ebola outbreak in the Congo Basin.
