Map B in Fig. 1 illustrates the smooth map of the estimated P. falciparum infection prevalence among school-aged children in Côte d’Ivoire. Lowest prevalences (around 45 %) were estimated for small urban aggregated areas in the south-east of the country, close to Abidjan, central-southern and central-western parts. Prevalences above 70 % were found in the north, central-east, south-east, west and south-west of Côte d’Ivoire. Map C in Fig. 1 shows the standard error of the predicted P. falciparum infection prevalence. High prediction errors were mostly found from central-west to central-east of the country.
