In Plano ISD, maintaining a safe and healthy environment for our students and staff is a top priority and a coordinated effort. The district works with the Collin County Health Department, as well as our students, staff, parents and healthcare professionals to manage communicable illnesses such as flu, and the same precautions are in place as we monitor the 2019 Novel (or new) Coronavirus. We all play an important role in managing flu season responsibly. More Information. En español.
