CDC Probes Lab Workers' Possible Anthrax Exposure

Healthcare workers in Dallas have been critical of protocols, saying they were not protected enough while caring for Ebola patient Thomas Duncan. New CDC guidelines are expected to include full-body suits known as personal protective equipment, with hoods that go over the neck.

"There was some skin that was exposed and some hair that was exposed. We want to make sure that that's no longer the case. That you have essentially everything covered," says Dr. Anthony Fauci of the National Institute of Allergy and Infectious Diseases.

A site manager would supervise workers putting their equipment on and taking it off.

"Putting it on you need to make sure your do it properly so every square inch is covered. As you take the equipment off making sure that you don't come into contact because if there is some sort of fluid on the front of the gown and you take it off and come into contact with that gown, that could be a deadly mistake," says Dr. Michael Anderson of University Hospitals in Cleveland.

Health care workers would also be required to rigorously practice getting in and out of their gear.
