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 ...
The latter require additional control measures to effectively prevent transmission. [ 13 ] [ 14 ] There are three types of transmission-based precautions: Contact precautions are intended to prevent transmission of infectious agents, including epidemiologically important microorganisms , which are spread by direct or indirect contact with the ...
The type of mask that is effective against airborne transmission is dependent on the size of the particles. While fluid-resistant surgical masks prevent large droplet inhalation, smaller particles which form aerosols require a higher level of protection with filtration masks rated at N95 (US) or FFP3 (EU) required.

Droplet transmission Transmission occurs when droplets containing microbes from the infected person are propelled a short distance through the air and deposited on the patient's body; droplets are generated from the source person mainly by coughing, sneezing, and talking, and during the performance of certain procedures, such as bronchoscopy.
Different diseases spread in different ways; some spread by only some of these routes. For instance, fomite transmission of COVID-19 is thought to be rare while aerosol, droplet and contact transmission appear to be the primary transmission modes, as of April 2021. [3] Coughs and sneezes can spread airborne droplets up to ~8 meters (26 ft).
Fecal–oral transmission is primarily considered as an indirect contact route through contaminated food or water. However, it can also operate through direct contact with feces or contaminated body parts, such as through anal sex. [19] [20] It can also operate through droplet or airborne transmission through the toilet plume from contaminated ...
(The Center Square) – President-elect Donald Trump, who is set to take office Monday, has made a series of promises of major executive actions on “day one” in office. One of the simplest and ...
Another important site for transmission is between members of the same household, [16] as well as hospitals due to the abundance of pathogens present. [88] Traffic vehicles are also a site for transmission, since the control of the pathogen there is harder due to the weak ventilation system and the high density of people. [88]
