title: Diagnosis of malaria: challenges for clinicians in endemic and non-endemic regions.
abstract: Malaria is a leading cause of morbidity and mortality worldwide. Prompt diagnosis and treatment are critical factors in reducing morbidity and mortality, as delayed treatment of malaria increases the risk of death. Microscopy has long been the standard of malaria diagnosis, but newer diagnostic tests now offer advantages in certain settings. Malaria diagnosis is complicated by the fact that acquired immunity to malaria can result in asymptomatic infections. In a symptomatic (febrile) patient, no existing malaria diagnostic test can distinguish malarial illness from parasitemia with concomitant fever of another cause. In this review we discuss the available malaria diagnostic tests, appropriate applications for each, and the challenges of malaria diagnosis in both endemic and non-endemic settings.
