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.
A new interactive map showing malaria vector resistance, P. falciparum gene deletions, and antimalarial efficacy and resistance has been released. Such information is critical to inform appropriate malaria prevention, diagnosis and treatment strategies and to guide the development of new tools.
WHO has produced the policy brief “Keeping the vector out: housing improvements for vector control and sustainable development” that contributes to recognize the importance of integrated approaches of vector control and aiming at highlighting effective housing interventions to prevent vector-borne diseases.
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 Development66顺彩票app. Strengthened political and financial commitments are required, along with new vector control tools and approaches.
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 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.

Global vector control response
The Global vector control response 2017–2030 was welcomed by the Seventieth World Health Assembly and a resolution was adopted. It provides strategic guidance to countries and development partners for urgent strengthening of vector control to prevent disease and respond to outbreaks.

Interventions and research
66顺彩票appDevelopers and manufacturers of public health vector control interventions can submit an application to WHO for evaluation. The appropriate evaluation pathway will depend on whether there is an existing WHO policy or if the intervention is a new tool, technology or approach. Evaluation can lead to inclusion on the prequalification list for vector control products that have been assessed by WHO and found to be acceptable, in principle, for procurement by UN and other international agencies and countries.
