AnoSTEP-Afrika is a collaborative, multicountry, multi-disciplinary project focused on understanding the distribution, behavior, and impact of Anopheles stephensi, a growing threat to malaria control in Africa. This project, conducted in collaboration with four African institutes and other partners aims to understand the contribution of An. stephensi to malaria transmission relative to native malaria vectors across a range of ecological zones spanning rural, peri-urban, and urban epidemiological settings in Djibouti, Ethiopia, Kenya, and Nigeria, to pinpoint factors driving invasion.
Anopheles stephensi is a mosquito species that can transmit malaria parasites to humans. Unlike most African malaria vectors that mainly thrive in rural or semi-rural settings, An. stephensi is highly adapted to urban environments. It breeds in artificial water containers such as barrels, tanks, and discarded containers places common in cities and towns.

To generate robust, actionable evidence on the biology, ecology and public-health impact of Anopheles stephensi across Africa to inform targeted surveillance and vector-control strategies.
A future where regional capacity, targeted surveillance, and evidence-based control measures prevent An. stephensi and other invasive vectors from reversing progress against malaria safeguarding urban and rural populations across Africa.
We ground every activity in rigorous, data-driven science. By combining field entomology, epidemiological studies, and advanced analytics, we generate reliable evidence that informs effective and sustainable malaria-control strategies.
We believe African scientists and institutions must lead Africa’s response to emerging disease threats. Through cross-country collaboration, we build local expertise, share methodologies, and empower national programs to respond effectively.
We believe in translating research into action. By engaging closely with policymakers and partners, we ensure our findings are turned into operational guidance, stronger surveillance, and evidence-based policy.
As the coordinating lead, the Ifakara Health Institute (IHI) hosted a Project Kick-Off Meeting in February 2025 in Dar es Salaam, Tanzania, bringing together all country partners in person, with colleagues from Lancaster and Sanger joining virtually.
Training on the platfrom VBDs 360 was done for the Kenya team. VBDs360 is an entomological surveillance used for the collection, analysis and storage of vector data..
Larvae collection is being done at the specified sentinel sites in Kenya. Collection was done in Turkana County.
Supporting the effective implementation of field activities through provision of essential tools.
The provision of this equipment aims to strengthen data collection, improve field operations, and support CHPs in executing their roles efficiently within their respective communities.
The team conducted data verification and field sampling in Wajir to enhance the quality and reliability of surveillance data. The activity aimed to validate existing records, assess data accuracy, and ensure consistency between field findings and reported information.
When passionate minds unite for a shared vision, real change becomes possible. By collaborating with AnoSTEP-Afrika, you join a community of scientists, innovators, and changemakers working to combat vector-borne diseases across Africa.
