Mosquito-borne diseases are a major global health threat, with nearly 80% of the world’s population at risk of infection. Climate change, conflict and human displacement are all growing in scale, increasing the spread of mosquito-borne diseases. A number of effective water, sanitation and waste management measures exist and can be implemented to prevent mosquito-borne diseases. A new WHO/UNICEF technical note provides practical information for implementing such measures with a focus on emergency contexts. The intended users are water, sanitation and hygiene (WASH) health partners and practitioners, national and local public health authorities and humanitarian and community-based organizations.
