Vector control

Why vector control?

Diseases transmitted by vectors account for around 17% of the estimated global burden of communicable diseases. Mosquitoes transmit malaria, dengue, chikungunya, lymphatic filariasis, yellow fever and Zika among other diseases; flies transmit leishmaniasis, onchocerciasis and sleeping sickness; and bugs or ticks transmit Chagas disease, borreliosis (Lyme disease), typhus and encephalitis. For most, prevention by targeting vectors is the first and best approach.

WHO to lead global vector control response

WHO has a new global strategy to reduce the burden and threat of vector-borne diseases through effective, locally adapted sustainable vector control. The Global vector control response 2017–2030 outlines a broad approach aligned with the 2030 Agenda for Sustainable Development. Strengthened political and financial commitments are required, along with new vector control tools and approaches.

Transformation to support innovation, efficiency, and quality for vector control

The WHO process for the evaluation of vector control products has been revised to better meet the needs of countries. This aims to accelerate product evaluation in order to enable continued scale-up and strengthening of vector control and address key challenges such as vector insecticide resistance.

Research as a foundation of the new strategy

Research is a core component of the Global vector control response 2017-2030. This includes developing new and improved vector control tools, technologies and approaches, and working out how to integrate and tailor these to local contexts.
