July 24, 2009 Croyle Welcomes 40 Outstanding High School Seniors to Visit Virus Laboratory

Twenty students fill a small lecture room chatting about what they have discovered while visiting the UT Austin campus. In rushes Dr. Maria Croyle, unbeknownst to them, with the announcement that something serious has happened in their small village here within this room and one person has fallen ill. While doing this she hands a somewhat shocked student a small card with a picture of the Ebola virus on it. She goes on to say that this individual rushes to her friends for help and in turn infects one of them (another student is given an Ebola card). Before they know it, 90% of the students in the room are holding Ebola cards. The exercise ends with approximately 75% of those infected holding "death" cards. This was one of several exercises used to illustrate how lethal pathogens spread and affect small isolated populations. Croyle then talked to the students about how these infections impact the state of Texas and the United States with respect to public health and economic policies. The class then toured her laboratory and got to witness how her group produces a recombinant vaccine against the Ebola virus from infecting cells used to grow the virus to final purification steps.

The Honors Colloquium is an annual event during which The University of Texas at Austin opens it's doors to high school seniors primarily from Texas high schools that will eventually be named National Merit, National Achievement, or National Hispanic Finalists and Scholars, and compete for the university's honor programs.
