Tanzania develops gene-based tool to curb malaria transmission

DAR ES SALAAM, Tanzania (MNTV) — Tanzania has announced a significant scientific breakthrough in its fight against malaria with the development of genetically modified mosquitoes designed to prevent disease transmission.

The Ministry of Health said local researchers have successfully created a new mosquito strain using gene-modification technology that prevents malaria parasites from developing inside the insect, thereby breaking the transmission cycle instead of eliminating mosquitoes altogether.

Officials described the development as the first of its kind on the African continent, created by Tanzanian scientists and tailored specifically to malaria strains circulating in local communities.

For decades, malaria has remained a major public health challenge in Tanzania, with traditional control measures such as insecticide-treated bed nets and indoor spraying facing growing resistance from mosquitoes. 

Authorities say the new approach could offer an additional layer of protection as existing tools lose effectiveness.

The project, initiated in 2023, is part of a broader research initiative aimed at building national capacity in advanced genetics and vector control. It has been supported through collaborative scientific training programs that helped strengthen local expertise in molecular biology.

Health officials emphasized that the innovation is not only a technological milestone but also a shift toward locally led research, ensuring solutions are adapted to regional environmental and health conditions.

They added that the technology remains under further evaluation to confirm its safety and effectiveness before potential large-scale deployment.

Tanzania, which ranks among the countries most affected by malaria globally, hopes the development could eventually complement existing prevention strategies and contribute to long-term disease reduction efforts across Africa.
