Mosquitoes engineered to halt transmission of dengue virus

0

A team of researchers, led by the University of California San Diego (CA, USA), have synthetically engineered mosquitoes to halt transmission of dengue virus to humans. The results of the study, published in PLOS Pathogens, could lead to a genetic approach to control the virus, along with other mosquito-borne pathogens.

Dengue virus is widespread across tropical and sub-tropical climates and is the leading cause of serious illness and death among children in many Asian and Latin American countries. It has cause increasing concern, with the Pan American Health organization recently reporting the highest number of dengue cases ever recorded in the Americas.

There are currently no specific treatments for the virus, and so prevention and control measures are of upmost importance.
