Rationale and Abstract

Case investigation (CI) of malaria cases and reactive case detection (RCD) of malaria infections are strategies that can contribute to malaria elimination in low-transmission settings. In Amhara region, Ethiopia, CI with RCD was conducted in 37 villages during the malaria transmission seasons in 2015-2016. P. falciparum or mixed malaria cases diagnosed at the health posts were considered index cases and were investigated (regarding socioeconomic characteristics, travel history, etc.). RCD with focal test and treat (FTAT) was conducted in the index case household and the ten closest neighboring households within a 100 meter radius. During the FTAT, all individuals in the targeted households were tested with a rapid diagnostic test (RDT) and all positives were treated with an antimalarial drug.
