Antibody reactivity against Ebola virus matrix protein as measured by luciferase immunoprecipitation system assay for the different sample sets in study of serologic prevalence of Ebola virus in equatorial Africa. Data were normalized against individual cutoff values determined for each experiment. Samples yielding reactivity >1 were counted as positive specimens. Error bars indicate 95% CIs. 1, Uganda 2007; 2, Cameroon 2007; 3, Ghana 2007; 4, Cameroon 2011–2012; 5, Republic of the Congo; 6,
