Observed age profiles of T. trichiura infection intensity in Southeast Asia (A) and Southwest Cameroon (B). Panel A contains EPG data from 11 studies (18 areas in four different countries) identified by a systematic review of epidemiological surveys of STH in Southeast Asia (Dunn et al., 2016) (compared to data from the St. Lucia study (Bundy et al., 1987)). Panel B reproduces that data provided by a study from Cameroon (Mbuh et al., 2012). EPG: eggs per gramme of faeces.
