Public health: Riordan High TB screening expands

Officials said the risk to the general public remains low, and that testing, contact tracing and follow-up care are aimed at preventing any additional active cases.

The school has been working through a clearance process so students and staff can return to regular, in-person routines while those who need treatment begin it under medical guidance.
