What schools in Texas have shut down for swine flu?

As of my most recent knowledge update in December 2022, there have not been any widespread school shutdowns specifically due to swine flu in Texas. Swine flu, also known as H1N1, was a global pandemic that occurred in 2009 and generally did not cause widespread school shutdowns in Texas. However, individual cases of swine flu may have resulted in temporary school closures or absences at the time. Since then, there have been seasonal influenza outbreaks, but significant school shutdowns due to influenza in Texas have generally not occurred unless public health officials determine that it's necessary to limit community spread.
