Study type | Observational |
A school-based, prospective, cohort study was conducted to evaluate the epidemiology of P. falciparum (Pf) infections in school-age children and determine the impact of the screen-and-treat approach on Pf infection and anemia prevalence among students in two different transmission settings. Investigators aimed to evaluate how frequently malaria rapid diagnostic tests (mRDTs) fail to detect low-parasite-density infections as well as whether low-density infections contribute to the burden and health consequences of Pf infection in school-age children and whether they contain gametocytes, the parasite stage required for transmission from humans to mosquitos.
