Asymptomatic Malaria—A Missed Opportunity in the Planned 2030 Malaria Elimination Programme in Ethiopia
Abstract: Background: Malaria intervention in Ethiopia has been strengthened significantly in the past decade with significant reduction in incidence and prevalence. However, continuous surveillance on malaria disease incidence was suggested for effective control and elimination. In difference to this suggestion, malaria elimination programme in the country is missing asymptomatic malaria as a prime target. Thus, the aim of this study was to determine prevalence of asymptomatic malaria and associated factors in …
