  1. Asexual parasite carriage was determined by microscopy, reading 100 microscopic fields, and 18S rRNA-based QT-NASBA that detects all parasite stages at an estimated sensitivity of 20 parasites/mL. Gametocytes were detected by microscopy, separately reading 100 microscopic fields, and Pfs25 mRNA based QT-NASBA that is gametocyte specific and has a sensitivity of 20-100 gametocytes/mL.
