摘要原文
In a study conducted in Singapore, a country prone to dengue outbreaks due to its climate and urban population, researchers examined the effectiveness of releasing male Aedes aegypti mosquitoes infected with Wolbachia (wAlbB strain) to reduce dengue transmission. These infected males, when mating with wild-type females, produced non-viable eggs, leading to vector suppression. Extensive field trials involving over 600,000 residents in four townships were conducted from 2018 to 2022. The results showed a 57% decline in total dengue incidence and a 64% decline in clustered dengue incidence. This approach offers promise for large-scale dengue control in regions facing rising dengue cases, providing a critical solution in combating the disease.
