Yet another area school district says it will not be opening its doors today due to widespread illness.

The Naselle–Grays River Valley School District says it is closed today because sickness has caused staffing shortages. Superintendent Josh Brooks made the announcement last evening.

This follows similar closures on Friday, when the Toutle Lake School District and some Portland-area districts also closed. Those districts said the closures were due to the spread of norovirus.
