Trinity Health System in Steubenville will now limit visitors by positioning employees at every entrance of every facility to ask the visitor several health questions before allowing entry.

Visitors under the age of 18 are no longer allowed, and they are asking that visitors refrain from visiting unless absolutely necessary.

Some entrances to Trinity East and West will be closed.

Signs will be posted.

The changes will take effect Monday to protect patients from the H1N1 virus.
