This online database captures school and office building closures related to incidences of COVID-19 since March 2020. Please note this list only includes traditional public schools; public charter schools are responsible for their own cleaning and sanitizing. The database does not include incidences that did not require cleaning or sanitizing (i.e., employee works remotely or the individual has not worked on-site recently).
* Following CDC recommendations, as of January 11, 2021, unless noted, buildings are not usually closed for cleaning; only the immediate or shared workspaces are closed for disinfection
