Wolbachia: Biological Control Strategy Against Arboviral Diseases

I. Mohanty, A. Rath and R. K. Hazra,  Genetically Modified and other Innovative Vector Control Technologies,  2021.

Arboviral diseases like dengue, chikungunya, and Zika are among the major causes of mortality and morbidity in human population. The limited control methods together with lack of antiviral therapies and effective vaccines have paved way for new approaches. One such approach to reduce the ever alarming conflagration of vector-borne diseases is based on biological strategy that reduces or blocks pathogen transmission in the vector. In this context, Wolbachia, an endosymbiont in mosquitoes, is explored as a novel and ecofriendly control strategy. Wolbachia seems to confer resistance to diverse RNA viruses protecting lives from virus-induced mortality. This review envisages the deployment of Wolbachia technology in controlling several arboviral diseases.
