Mosquitoes, flies, bugs and other vectors transmit viruses, parasites and bacteria that infect millions of people globally. They cause many diseases, including malaria, dengue, leishmaniases, Chagas disease and Zika virus disease. WHO has developed a new strategy to strengthen vector control worldwide. Member States welcomed this integrated approach at the 2017 World Health Assembly and adopted a resolution to support the strategy. This brochure is a high-level summary of the rationale and elements of the Global vector control response 2017–2030.
