This 15-year-old maintains a website that tracks coronavirus cases in schools

When William Wu’s older sister left for her freshman year at Georgia Tech in August, the 15-year-old from Shrewsbury, Mass., noticed that his mother spent a good amount of time looking at the university’s covid-19 dashboard. The numbers, big or small, gave her some peace of mind.

Wu wondered if similar information was available for public high schools. He was about to begin his sophomore year at Shrewsbury High with a hybrid learning model, featuring two days of in-person learning per week, and thought it could be useful to know how many cases derived from schools in other states.
