There are over 3,000 species of mosquitoes, but only a few are significant from an epidemiological perspective. The Anopheles mosquitoes are the primary vectors of malaria. Aedes mosquitoes, including Aedes aegypti and Aedes albopictus, are responsible for spreading dengue, Zika, chikungunya, and yellow fever. Culex mosquitoes transmit West Nile virus and other encephalitis-causing viruses.
