Variation in exposure risk of individuals across sampling nights. The estimated average number of Anopheles gambiae s.l. bites per person per night using the time spent outdoors by humans observed in 2017–2018 and the number of mosquitoes attempting to feed outdoors from Cascades region human landing catch data recorded in 2016–2017 [19]. a The number of bites across weeknights for the respective age cohorts: under 10-year olds (blue), 11–20-year olds (light blue), 21–50-year olds (light green) and over 50-year olds (dark green). Under 10-year olds consistently receive few bites relative to the older population. The estimated 95% confidence interval (using 95% CI from HLC data, Sanou et al. pers. comm.) and mean number of An. gambiae s.l. bites (points) received for two people in Niakore (b) and Toma (c) respectively across different sampling months and weeknights. Additional file 1: Fig. S3 provides individual data for the Niakore and Toma populations observed in this study
