A look at how many Washington University students tested positive for COVID-19, quarantined, broke guidelines and eventually got vaccinated during a tumultuous year.

At a point approximately halfway through the semester, 178 undergraduate students have tested positive, a figure equal to 83.18% of last semester’s semester’s total undergraduate cases.

Since the start of the spring semester, three large clusters of COVID-19 cases have been reported by Washington University, and the Office of Student Conduct and Community Standards has adjudicated at least 117 student conduct cases related to COVID-19 violations.
