The CDC and USAMRIID treat any room containing the Ebola virus as a Level 4 Hot Zone. Here is what you do when entering a Level 4 Hot Zone:
Level 1, Locker room: Strip completely down to skin and put on a sterile scrub suit and surgical cap and walk barefoot into Level 2
Level 2, Airtight room with negative pressure: Put on socks and walk into Level 3
Level 3, Staging area: Put on surgical gloves then tape the scrub suit to the gloves and socks. Then walk into an antechamber to Level 4.
Antichamber: Put on a Chemturion biological space suit, which has brown rubber gloves attached by gaskets at the cuffs. Put on helmet and close suit with an oiled ziplock zipper. Attach air hose. Gather what tools you will need, unplug air hose and walk into the Level 4 Air Lock
Level 4 Air Lock/DeCon Shower: Not much to do here except when leaving. Walk through Air Lock and enter Level 4 Hot Zone.
Level 4 Hot Zone: Attach air hose and put on rubber boots. Detach air hose, walk to your work station and attach air hose.
I guarantee you the protocol for entering Mr. Duncan's room at Texas Health Presbyterian Hospital was nothing anywhere like this. Your average American Hospital is not prepared to deal with Ebola. Only a few hospitals are really prepared and trained for Ebola.
