From: Malaria outbreak in Riaba district, Bioko Island: lessons learned
Malaria prevalence estimates from MIS and from the outbreak survey. Data from MIS were plotted separately for Riaba and for the rest of the island. Error bars illustrate the 95% confidence intervals. Individuals with history of off-island travel in the previous 8 weeks were excluded from the MIS data to control for the confounding effects of malaria importation [22]
