In Cambodia, 2 feasibility studies found that VMWs were able to progressively improve their skills in using G6PD biosensors and provide primaquine for radical treatment of Plasmodium vivax malaria [63], and to perform dengue antigen–antibody RDTs, combined malaria/C-reactive protein (CRP) tests, and multiplexed biosensors [66]. Here, G6PD is linked to malaria.
