Integrating this approach into current routine dengue control efforts could reduce dengue incidence. However, challenges such as implementation costs, the need for country ownership, alignment of released mosquitoes with local mosquito populations, increased education and sensitization for government authorities and the public on the benefits of <em>Wolbachia</em>, identifying international funding partners, and recognizing areas where the strategy may be less effective due to environmental or socio-political factors must be addressed. Furthermore, <em>Wolbachia</em> replacement must focus in areas with high population density and high dengue incidence because it is not feasible to cover all endemic areas. Establishing robust surveillance systems to monitor efficacy against different dengue serotypes is also critical. Despite these challenges, the <em>Wolbachia</em> strategy is the one of the most promising developments in dengue prevention to date.
