Biological control company Oxitec recently launched Sparks, a new platform designed to rapidly scale Wolbachia replacement technology to take on dengue fever.

Backed by a multi-million-dollar investment from the Gates Foundation, Sparks adds to Oxitec’s Aedes aegypti technology, called Friendly, which is taking on dengue fever in Brazil. 

With mosquito-borne diseases on the rise, Oxitec’s Friendly mosquitoes are designed to suppress populations of disease-spreading mosquitoes and, in turn, reduce biting and the threat of disease transmission. Wolbachia-carrying mosquitoes are designed to spread Wolbachia bacteria into the local mosquito population to limit the ability of the remaining infected mosquito population to transmit dengue. 

The platforms are designed for specific settings and intervention types, and provide options for governments and communities seeking suppression, replacement or hybrid approaches using both.

Our guest on the podcast this week is the CEO of Oxitec, Grey Frandsen.
