Improved limit of detection for zoonotic and surveillance using reverse transcription for total nucleic acid preserved samples or dried blood spots.

Background: Zoonotic and symptomatic and asymptomatic infections occur across endemic areas of Southeast Asia. Most infections are low-parasitemia, with an unknown proportion below routine microscopy detection thresholds. Molecular surveillance tools optimizing the limit of detection (LOD) would allow more accurate estimates of zoonotic malaria prevalence.
