With Online Games, High School Students Learn How to Rein in Disease Outbreaks

High school students investigate Ebola-like outbreaks and administer vaccines through Outbreak!, a new summer course at Illinois that uses online games to encourage critical thinking about fighting infectious diseases.

Dr. Johnson-Walker said she hopes to interest students in public health issues and how they relate to disease emergence, the environment, education and the culture of the area where a new outbreak occurs.
For example, students analyze and discuss the 2014-16 Ebola outbreak in West Africa, learning what can happen in places with limited resources and public health infrastructure, and how culture and human behavior can interfere with strategies to stop an outbreak’s spread anywhere in the world.

The online interactive game Vax! teaches students which strategies work best to prevent new infections.
“It looks at networks and how people interact with other people,” she said. “Given a limited supply of vaccine, a player must select which individuals to vaccinate to break disease transmission.”
A game from the Centers for Disease Control and Prevention, Solve the Outbreak, walks students through scenarios involving a fever similar to Ebola or a food-borne illness and asks them to track down the source of the outbreak. As a “disease detective,” each player analyzes data and weighs the next steps to make sure the outbreak does not resurface.
This teaches students the importance of herd immunity, Dr. Johnson-Walker said, and about real-life obstacles – such as individuals who choose not to vaccinate – that make it more difficult to stop the spread of infection. These are important concepts when thinking about the development of new vaccines or the best ways to distribute vaccines to protect the larger population, she said.
Another game, Influenza, requires players to make policy and resource decisions. Should they close schools? Ask people to stay home? Is international travel involved?
These decisions show how the environment plays a role in emerging diseases, Dr. Johnson-Walker said. For example, success in eradicating smallpox was due in part to the lack of a wildlife carrier that could pass the disease to more humans. An outbreak like Ebola, where the way people interact with wildlife can affect the spread of a disease, makes it much more challenging to control that disease, she said.
“How we respond to a new disease is going to look very different depending on where in the world it emerges,” Dr. Johnson-Walker said.
The Outbreak! course is supported by a grant through the university’s Center for African Studies as part of the Global Reach Area Studies Program initiative.
