Cleveland (AP) -- Ohio hospitals want state health officials to drop a rule that says health care workers should wear special face masks when treating flu patients.
What are called N95 masks form a tight seal around the nose and mouth and are designed to stop airborne viruses.
The Ohio Hospital Association argues that there's not enough evidence that flu is spread through the air, besides through contact.
The trade group says N95 masks are largely unnecessary and is asking the Ohio Department of Health to ease its recommendation on using them.
The hospital association is waiting for an answer from the department.
State offices were closed monday for the Columbus Day holiday.
The U.S. Centers for Disease control and prevention also supports the use of N95 masks.
