Additional information and definitions

Vaccination Data: The “fully vaccinated” category reflects employees and students who have been on campus in the last 30 days and are fully vaccinated. The “in process” category reflects students who are in the process of becoming fully vaccinated in accordance with university policies. Affiliates are excluded from these percentages if they have an approved medical or religious exemption or if they have not been on campus in the last 30 days.

Positive Cases: The number of individuals within the Johns Hopkins University community who have tested positive for COVID-19. Student data includes undergraduates, graduate students, and medical students. Post-doctoral fellows, medical residents and clinical fellows, and medical house staff are included in the employee counts. Johns Hopkins Health System (including Johns Hopkins Hospital) employees are not represented in these counts. The data displayed on the dashboard correspond to date of test result and not date of sample collection.

Tests ConductedThis includes: 1) tests conducted by Johns Hopkins University for asymptomatic (i.e., no symptoms of COVID-19) students and employees; and 2) tests conducted by Johns Hopkins University for students and employees experiencing symptoms associated with COVID-19. The asymptomatic testing program was significantly expanded in January 2021.
