This video shows how scientists in Bangladesh are testing fruit bat populations to determine whether they are infected with Nipah virus - a potentially deadly virus when passed on to humans.

Students explain how a vector can transmit a virus to a host and give examples of vectors and the viruses they might carry. Students will learn how researchers use DNA sequencing to create a powerful tool to track the spread of the Zika virus around the world.

In this lesson, students will work to develop a prevention plan for an American Indian reservation that is experiencing a new occurrence of West Nile virus infection, while taking into consideration the cultural and environmental implications relevant to this population. To successfully complete these activities, the students should have some knowledge of enzyme-linked immunosorbent assay (ELISA), polymerase chain reaction (PCR), and gel electrophoresis.

This brief video lesson discusses how the Ebola virus spreads and frequently results in outbreaks. Discussion/assessment questions and suggested supplemental resources are also included.
