Using incredible videography, photos, animation and graphics, this information-packed episode of Real World Science introduces students to biological vectors. Viewers will learn that biological vectors carry and transmit diseases that affect plants, animals and humans. The program explores various types of diseases spread by vectors including, Zika, Lyme disease, Malaria, Dengue and Yellow Fever. The video vividly demonstrates how a mosquito sucks blood from a human and then explains how a pathogen is transmitted. Students will learn how scientists who study insects and infectious diseases can use the information they gather to help control and prevent the transmission of vector-borne diseases around the world.
