Yoel Lubell and colleagues consider the costs and benefits of multiplex malaria/CRP tests that are now commercially available in terms of (i) the improved health outcomes for patients with bacterial illnesses; (ii) the costs of antimicrobial resistance averted; or (iii) the economic benefits of better management of remaining malaria cases and shorter malaria elimination campaigns. They conclude that a multiplexed malaria/CRP test could be highly cost-effective and utilize the well-established funding and distribution systems already in place for malaria RDTs.

Drug-resistant infections caused by Enterobacteriaceae, a family of Gram-negative bacteria, account for a high and increasing disease burden amongst hospitalised neonates in Southeast Asia; carbapenem-resistant strains are particularly important because of limited antibiotic treatment options.
