Kristy Collins, VBI's education program manager for grades K-through-12, said about 3,000 of the estimated 30,000 Scouts at the Jamboree have participated so far. The labels are waterproof, enabling Scouts to participate even when they're doing other activities, such as rafting or learning how to SCUBA dive.
Some of the participants' gamer tags have included names like "B1ack.Plague" and "blaime.the.zombie."
It's not the first time technology and the undead have banded together. In 2005, the Humans vs. Zombies tag game was made popular at Goucher College in Maryland. It quickly spread to college campuses and communities nationwide. That version uses socks, foam-dart guns and red or green bandanas and requires reporting "tagged" zombies on a website.
The Virus Tracker system has been used twice before at the USA Science and Engineering Festival. This week marks the first time the Virus Tracker app has been used and the first time the institute has been to the Scouts Jamboree, Collins said.
Researchers are using data collected at the Jamboree to create an "infection tree" to show how individual Scouts spread the zombie virus within their population. The data will show how diseases such as the flu can become pandemics.
At times, "vaccines" are sent out through the system to turn the zombies human again if the Scouts answer an epidemiology question correctly. The Virus Tracker keeps count of things such as the number of infected and inoculated participants. Scouts without access to smartphones can still register by computer at the tent and distribute labels to other Scouts, thereby "infecting" them with the "virus."
"The first thing everybody says is 'is it real?'" Collins said. "And we say, no it's not real. We're not giving you the flu. We kind of laugh about that."
The Scouts are then invited to help spread the zombie virus.
"And then they're like, 'yeah, man, I really do!" Collins said.
