Dengue fever has become a major threat to the health of the planet because there is no effective treatment or widely available prophylaxis.[1] Its spread is exacerbated by climate change, urbanization and population movements.[1] Although malaria elimination has been reported in 14 countries, reducing the risk to human health of vector-borne diseases remains a serious challenge.[1] The disease is transmitted by the mosquito Aedes aegypti and, to a lesser extent, Aedes albopictus.[5] The worldwide incidence of dengue fever has increased dramatically, with approximately half of the world's population now at risk.[5] An estimated 100 to 400 million infections occur each year, with more than 80 percent generally mild and asymptomatic.[5] The main strategies to address mosquito-borne health risks are vector surveillance, chemical spraying, and biomedically modified vector experiments.[1]
