About AnoSTEP-Afrika

A collaborative, multi-country research initiative tackling the emerging threat of Anopheles stephensi — a rapidly spreading malaria vector in Africa.

What is AnoSTEP Afrika?

AnoSTEP Afrika is a multi-country, multi-disciplinary investigation of Anopheles stephensi across diverse ecological settings in Africa. Conducted in Kenya, Djibouti, Ethiopia, and Nigeria, the project is coordinated through Ifakara Health Institute (Tanzania) with support from Lancaster University, University of Glasgow, and Wellcome Sanger Institute.

The project spans 4 years (January 2025 – December 2028) and is supported by Wellcome Trust. AnoSTEP Afrika seeks to evaluate the role of Anopheles stephensi in malaria transmission across diverse ecological and epidemiological settings, especially in urban and peri-urban areas.

Who We Are

AnoSTEP Afrika is a collaborative, multi-country, and multi-disciplinary project focused on understanding the distribution, behavior, and impact of Anopheles stephensi, a growing threat to malaria control in Africa.

Conducted in collaboration with four African institutes and international partners, the project explores the role of An. stephensi in malaria transmission relative to native vectors across ecological zones in Djibouti, Ethiopia, Kenya, and Nigeria.

The findings will strengthen the evidence base on the impact of this invasive vector, inform targeted response strategies, and guide research, innovation, and policy.
