What are the 3 major portals of entry for disease?
Portals of entry into the human body include:
- Inhalation (via the respiratory tract)
- Absorption (via mucous membranes such as the eyes)
- Ingestion (via the gastrointestinal tract)
- Inoculation (as the result of an inoculation injury)
- Introduction (via the insertion of medical devices)
What are the three most common modes of transmission in health care settings?
There are three types of transmission-based precautions–contact, droplet, and airborne – the type used depends on the mode of transmission of a specific disease.
What are the 5 basic modes of transmission of infection?
The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.
What is the most common portal of entry?
Mucosal surfaces are the most important portals of entry for microbes; these include the mucous membranes of the respiratory tract, the gastrointestinal tract, and the genitourinary tract.
What are the 5 portals of entry?
Portals of entry into the human body include inhalation, absorption (via mucous membranes, eyes or naughty bits), ingestion (via the gastrointestinal tract), inoculation (as the result of puncture or trauma) or introduction (insertion of medical devices).
What are the six chain of infection?
The 6 points include: the infectious agent, reservoir, portal of exit, means of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting the chain at any link.
