This study was conducted from March 2012 to December 2013 in four clinics and seven villages along the China–Myanmar border. The presence of gametocytes in patients through 14 days after DHA-P treatment suggests that the incorporation of a single dose of primaquine for clearing gametocytemia should be considered for blocking parasite transmission.
