Fig. 3From: Co-infection of Plasmodium falciparum and Schistosoma mansoni is associated with anaemiaPrevalence of malaria parasite carriage and infection intensity. The prevalence of malaria was stratified by gender (A), age groups (B), and by communities where schools were located (C). The infection intensity was classified as light infection (1–499 parasites/μl of blood), moderate infection (500–1999 parasites/μl of blood) and heavy infection (≥ 2000 parasites/μl of blood) (D). The bar chart represents the percentage (%) prevalence with 95% confidence intervals (i.e., error bars). The dark (black) bars are the uninfected group and the light bars represent the infected groupBack to article page
