With on-campus classes resuming in the midst of the pandemic, it became crucial for Georgia Tech’s Health Department to curb the virus spread by urging exposed individuals to isolate.

While on an average, there are 1000 people who may have come in contact with an infected person, the Georgia Tech Health Department has the resources to contact only up to 5 people per infected person. It is then critical to shortlist people who are most vulnerable and likely to be infected.

How might we prioritize contacting high-risk individuals exposed to the COVID-19 virus?
