Thanks to Charles Simmins for tweeting this link to a real eye-opener at the KSA MOH page: Infection prevention and control precautions when caring for patients with probable or confirmed novel coronavirus (nCoV infection). It's a PDF dated May 15, 2013, and may help to explain how MERS got such a firm foothold in Saudi hospitals.
For a more current and detailed protocol, issued this month, download this. Some guidelines remain the same, like this advice on patient placement:
• Place patients with suspected, probable or confirmed MERS-CoV infection in
adequately ventilated single rooms or Airborne Precaution rooms if available.
• The rooms used for isolation (i.e. single rooms) should be situated in an area
that is clearly segregated from other patient-care areas.
• When single rooms are not available, put patients with the same lab
confirmed diagnosis together.
• If this is not possible, place patient beds at least 1 m apart.
One meter still seems dangerously intimate to me, but infection-control experts may find that perfectly adequate.
