New approach aims to reduce disease transmission by quickly spreading a gene variant that occurs naturally in some mosquitoes



Summary

A novel disease control strategy proposes rapidly spreading a naturally occurring gene variant within mosquito populations to reduce disease transmission. Unlike previous gene-editing approaches, this method leverages existing genetic diversity. By increasing the prevalence of a beneficial gene, it could disrupt the mosquito’s ability to transmit viruses like dengue or Zika. This “gene drive” approach aims to naturally curb disease spread without relying on artificial genetic modifications, potentially offering a more sustainable and environmentally friendly solution to combat mosquito-borne illnesses. The focus is on amplifying a pre-existing, advantageous trait to make mosquitoes less effective vectors.
