A physician office cannot provide an airborne infection isolation room. Which measure reduces airborne transmission there?

1. Where engineering resources are limited, airborne isolation rooms may simply not exist. 2. The stated fallback is to mask the patient and place that patient in a private room, such as an office examination room, with the door closed. 3. Staff are provided with N95 or higher level respirators, or with masks if respirators are not available. 4. This holds until the patient is transferred to a facility with an isolation room or returned home, as judged medically appropriate. 5. An open waiting area exposes everyone waiting, and a door left ajar defeats the containment the private room provides. 6. Sending the patient away without arrangements abandons the care the patient came for. _Source: CDC Guideline for Isolation Precautions: Preventing Transmission of Infectious Agents in Healthcare Settings (2007), Part III, section III.B.3.
