Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
A poster outlining precautions for airborne transmission in healthcare settings. It is intended to be posted outside rooms of patients with an infection that can spread through airborne transmission. [1] Video explainer on reducing airborne pathogen transmission indoors
Eye protection, hair coverings, and surgical masks are also required; all PPE, eye protection, hair coverings, and masks must be properly fitted to the face, covering eyes, nose, hairs, and mouths, be pre-tested in order to assure they are the correct size, and be sanitized or disposed of after contact with patient.

Airborne transmission: Dissemination can be either airborne droplet nuclei (small-particle residue {5 μm or smaller in size} of evaporated droplets containing microorganisms that remain suspended in the air for long periods of time) or dust particles containing the infectious agent. Microorganisms carried in this manner can be dispersed widely ...
[7] [8] In the airborne route, the droplets that are small enough for people to inhale are 0.5 to 5 μm in diameter and inhaling just one droplet might be enough to cause an infection. [4] Although a single sneeze releases up to 40,000 droplets, [9] most of these droplets are quite large and will quickly settle out of the air. [4]
Respiratory droplet transmission is the usual route for respiratory infections. Transmission can occur when respiratory droplets reach susceptible mucosal surfaces, such as in the eyes, nose or mouth. This can also happen indirectly via contact with contaminated surfaces when hands then touch the face. Respiratory droplets are large and cannot ...

airborne transmission – very small dry and wet particles that stay in the air for long periods of time allowing airborne contamination even after the departure of the host. Particle size < 5 μm. droplet transmission – small and usually wet particles that stay in the air for a short period of time. Contamination usually occurs in the ...
