Note: This dataset reflects public and non-public K-12 schools in Maryland that have COVID-19 outbreaks. Data are based on local health department reports to MDH, which may be revised if additional information becomes available. This list does not include child care facilities or institutes of higher education.
Schools listed meet 1 or more of the following criteria:
Classroom/cohort outbreak definition:
At least two confirmed COVID-19 cases among students/teachers/staff within a 14-day period and who are epidemiologically linked, but not household contacts; or
School-wide outbreak definition:
Three or more classrooms or cohorts with cases from separate households that meet the classroom/cohort outbreak definition that occurs within 14 days; or
Five percent or more unrelated students/teachers/staff have confirmed COVID-19 within a 14 day period (minimum of 10 unrelated students/teachers/staff).
Cases reported reflect the current total number of cases. Schools are removed from the list when health officials determine 14 days have passed with no new cases and no tests pending. Archival data is available through the COVID-19 open data catalogue.
These data are updated weekly on Wednesdays during the 10 a.m. hour. MDH is continuously evaluating its data and reporting systems and will make updates as more data becomes available.
