Saving Baby Elephants from a Lethal Virus
Blood Samples and Trunk Washes
Regular blood draws and trunk washes are done to catch an infection before it turns deadly.
Blood samples are taken directly from a blood vessel in an elephant’s ear.
Trunk washes involve lifting the trunk up and flushing a sterile saline solution into one nostril. A one-gallon plastic bag is placed over the tip of the trunk. The trunk is lowered so that fluids drain out of the trunk and into the bag, which are then sent for processing in a lab.
Retrospective of other cases suggest that low levels of virus in blood is detectable up to 10 days before clinical signs emerge.

How can something we cannot see harm us? How can we protect ourselves from getting a disease? Activities in the Invisible Threats guide will help you and your students learn about and understand infectious diseases—how they are contracted and prevented. (8 activities)
Paul D. Ling, Ph.D., a microbiologist at Baylor College of Medicine, is a leading global expert on Elephant Endotheliotropic Herpesvirus (EEHV), a disease that is killing baby Asian elephants. Join him as he discusses the virus, key discoveries, and a treatment protocol developed by his research team which keeps the elephants alive.
In this storybook, young students track a mysterious illness that is killing baby elephants. They learn how doctors and scientists identified the pathogen, found a treatment and are working to make a vaccine.
