Age-specific parasite load in humans based on quantitative PCR targeting for Plasmodium spp. 18S rRNA genes in study of zoonotic and anthroponotic Plasmodium spp. circulation between wild primates and Indigenous community, Peruvian Amazon, 2007–2020. A) Smoothed regression of log-transformed parasite DNA concentration, by age, in 49 persons. B) Boxplot comparing parasite loads between children <8 years and older persons. Higher parasite loads occurred in younger age groups. Horizontal lines within boxes indicate medians; box tops and bottoms indicate interquartile range (25th–75th percentiles); error bars indicate 1.5 × interquartile range.
