The Sparks initiative

Scale Wolbachia.
Eliminate dengue.

Sparks is the end-to-end platform built to help governments take Wolbachia from pilot to national program — in pursuit of protecting one billion people from dengue by 2040.

The dengue crisis

A growing emergency — and traditional tools are losing ground.

Dengue cases have risen ten-fold in seven years. Aedes aegypti is spreading into new climates, chemical insecticides are failing, and existing programs are reactive, fragmented and expensive.

Wolbachia is proven

Mosquitoes carrying natural Wolbachia block dengue — and the effect sustains itself.

Releasing mosquitoes that carry dengue-blocking Wolbachia spreads protection through the local population. The result is a proven, sustained reduction in dengue, demonstrated across multiple countries.

Releases, then self-sustaining
Once established, Wolbachia persists in the mosquito population on its own — follow-up treatment may be needed in some settings.

Fewer dengue cases, and 86% fewer hospitalizations — the strongest evidence yet that Wolbachia works.
