Dengue is a mosquito-borne viral infection, found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas. The WHO has estimated an approximate 390 million dengue virus infections every year.
Researchers from Queensland, Australia injected Aedes aegypti mosquitoes with a bacteria called Wolbachia, which prevents them from being infected by dengue viruses.
Wolbachia is a fast-spreading bacteria and passes down mainly from insect mothers to their children. To date, Wolbachia has been found to exist in at least 40 percent of all insect species, making it one of the most successful microbes on the planet.
Since Wolbachia spreads very quickly, even a small number of Wolbachia carrier mosquitoes released into a neighborhood can transform almost all of the local insects making them dengue-free within a few months. @wmpglobal
