      contact. Transmission occurs when a person inhales droplet nuclei containing . M. tuberculosis, and the droplet nuclei traverse the mouth or nasal passages, upper respiratory tract, and bronchi to reach the alveoli of the lungs (Figure 2.2). M. tuberculosis. is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter.

      Transmission based precautions are work practices that are used when the route of transmission of an infectious agent is not interrupted by using Standard Precautions alone. Use transmission-based precautions when caring for patients known or suspected of being infected with agents transmitted by contact, droplet or airborne routes.

This is where infection prevention and control strategies can be most successful. Microorganisms are transmitted in health care settings by four main routes: • Contact • Droplet • Airborne
