The Tennessee Department of Health (TDH) will not issue data on Covid-19 cases and tests on Sunday due to an unplanned shutdown of the state surveillance system, according to a statement released this afternoon.
The TDH uses the National Electronic Disease Surveillance System Base (NBS) to manage local, state and territorial health departments’ disease data reports, and sends it to the Centers for Disease Control and Prevention, according to a news release. This system houses data for all reportable diseases in the state, including Covid-19.
Around 3 p.m. Sunday, the NBS element that imports laboratory results encountered an unexplained shutdown, the health department said. The issue was resolved by TDH and state technology teams, and lab imports to NBS were restarted by noon, the health department said.
However, due to the backlog and unexpected shutdown, a limited number of Covid-19 results were imported into NBS in the past 24 hours. Since the data is incomplete, TDH made the decision to not release numbers today.
TDH notes that technical difficulties may also cause a delay in notifying those who have tested positive for Covid-19.
