Nairobi, Kenya – The Bill & Melinda Gates Foundation has firmly denied reports circulating on social media alleging that it is behind the rapid increase in mosquitoes in Kenya.
In a statement released on Monday, February 9, 2026, the foundation categorised the claims as “false”, distancing itself from rumours of unauthorised biological interventions.
Viral Allegations
The clarification came after Senior Counsel and politician Paul Muite took to X (formerly Twitter) accusing the foundation of releasing genetically modified mosquitoes in Nairobi.
Muite wrote:
“Our Capital City Nairobi is now flooded with mosquitoes released from your laboratories to eliminate the malaria-carrying ones we’re told. We believe your genetically modified mosquitoes are designed to harm us. They’re now busy biting children and the elderly.”
His post triggered widespread reactions online, with many Kenyans citing anecdotal instances they believe point to mosquito mass production and release.
Foundation’s Response
In a brief statement on X, the Gates Foundation emphasized that it does not engage in the physical release of mosquitoes or operate vector-control laboratories in Kenya.
“The Gates Foundation is aware of social media posts claiming that we release mosquitoes in Kenya. This claim is false. The Gates Foundation does not release mosquitoes, operate laboratories that do so, or run vector-control activities in Nairobi or anywhere else.”
The foundation stressed that all its work in Kenya is conducted in accordance with national laws and regulatory oversight, supporting Kenyan-led priorities rather than dictating health policy.
“In Kenya, malaria prevention and control efforts are led by Kenyan authorities and institutions, in accordance with national laws and regulatory oversight. The foundation supports Kenyan-led priorities transparently and responsibly, working alongside governments, researchers, and public health partners.”
Malaria Control in Kenya
The denial comes at a time when malaria remains a major public health challenge in the region. The National Malaria Control Programme (NMCP) under the Ministry of Health oversees prevention measures such as the distribution of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS).
While the Gates Foundation funds global research into innovative tools like the World Mosquito Program and Target Malaria, it clarified that operational activities in Kenya are managed by local experts and regulated by the state.
Conclusion
The Gates Foundation’s statement seeks to dispel misinformation and reaffirm its role as a supporter of Kenya’s public health priorities. As malaria continues to pose a threat, the focus remains on strengthening locally led, transparent, and regulated interventions to protect vulnerable communities.
