Adapting Africa’s vector surveillance systems to monitor gene-drive mosquitoes in malaria control

Résumé fourni par la source

Gene-drive mosquitoes could transform malaria control in Africa, but their rapid, autonomous spread requires rigorous post-release monitoring. Most malaria-endemic countries already conduct some entomological surveillance, although it is often limited, fragmented, and externally funded. Molecular diagnostics are also expanding but remain mostly research focused and ad hoc . These imperfect systems offer workable foundations for strategic upgrades to support essential gene-drive monitoring. Priority investments should strengthen field-entomology, high-throughput genotyping for drive alleles and resistance, technical expertise, and integrated data for decision-making. Fortunately, first-generation gene drives already align with common phenotyping and genotyping workflows, avoiding major infrastructure overhauls, and permit simpler evaluation metrics than conventional interventions. This feature review examines key technical and operational considerations for monitoring gene drives and recommends how countries can adapt their vector surveillance systems to effectively monitor gene-drive mosquito releases.
