This tutorial introduces students to vector-borne disease with a focus on dengue fever, which is transmitted by mosquitoes. Students also learn about strategies designed to stop the spread of disease by interfering with the mosquito life cycle.

Infectious disease vectors include mosquitoes, ticks, and flies. The vector’s life cycle is critical to infection. In this Click & Learn, students explore different strategies for disrupting the life cycle of Aedes mosquitoes, which are vectors for dengue fever. Students then examine data shown in graphs about the impact of one mosquito eradication program carried out in Fortaleza, Brazil, from 1986 to 1998.
