Effectiveness of a malaria surveillance strategy based on active case detection during high transmission season in the Peruvian Amazon
To assess the short-term effectiveness of household-based malaria active case detection (ACD) interventions in four riverine communities of the Peruvian Amazon.
The proportion of malaria infections detected by field microscopy in consecutive surveys was compared to the total malaria infections detected by delayed quantitative real-time polymerase chain reaction (qPCR).
A cohort study was conducted in June–July 2015 in Mazan, Loreto. Four consecutive ACD interventions at intervals of 10 days were conducted in four riverine communities. In each intervention, all inhabitants were visited at home, and finger-prick blood samples collected for immediate diagnosis by light microscopy and on filter paper for later analysis by qPCR.
