Excerpted from NOVA: Surviving AIDS, this video segment showcases the work of Drs. David Ho and Stephen O'Brien. By examining the "outliers" -- in this case, people like Steve Crohn, whose cells repeatedly resisted HIV infection -- Ho and his colleagues found a genetic mutation that prevents the HIV virus from entering the cell. This video segment includes animation of HIV entering a white blood cell through the CD-4 and CCR-5 receptors on the cell's surface. Some individuals have no CCR-5 gene, which means that HIV cannot enter their cells. Scientists are using this new information in the development of an AIDS treatment.

Zika, unlike Ebola, is less commonly spread by human-to-human contact. Instead, mosquitos are the root cause. Brazil has recently implemented mosquito controls to prevent the transmission several of viral diseases, including Zika. As the world's population grows and spreads geographically, human interaction with new wildlife opens up greater opportunity for zoonotic disease to spread.

A New Foe Emerges - Nipah | Spillover - Zika, Ebola & Beyond: Part 7

In 1988 Southeast Asia faced it's own battle with Nipah, a fruit bat-borne disease that kills more than three quarters of those infected. Nipah is only contracted in Bangladesh between the months of December and March, and this was a puzzle at first. It turns out that it is during these months that date palm sap, a national delicacy, is collected. Fruit bats, too, drink this sap, and the sap is thus the vehicle of Nipah transmission. Jonathan Epstein monitors bats in Bangladesh in an effort to prevent Nipah from becoming a global pandemic.
