The TCS COVID Tracker is updated throughout the day as cases are identified. This tracker was first posted on August 25, 2021. Although the Alabama Department of Public Health bears the responsibility of quarantining individuals, parents and employees may choose to self-quarantine. The quarantines/isolations noted in the tracker reflect those who have received a diagnosis of a confirmed positive case (isolation) and those who either (a) are under ADPH quarantine or (b) have chosen to self-quarantine and notified school officials of this decision.
