Abstract:
An observational pilot in walk-in clinics assessed workflow impacts of personal protective equipment (PPE) use for COVID-19 cases. PPE added time, waste, and cost despite a low incidence period of illness. Limited supporting data for contact transmission and operational barriers suggest ambulatory PPE guidance for COVID-19 warrants modification.

Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
