What are the 3 major portals of entry for disease?
An anatomic site through which pathogens can pass into host tissue is called a portal of entry. These are locations where the host cells are in direct contact with the external environment. Major portals of entry are identified in Figure 3 and include the skin, mucous membranes, and parenteral routes. Figure 3.
What is it called when a disease spreads?
86. MODES OF TRANSMISSION READING. The spread of a disease from one person to another is called transmission. There are many different types of transmission and each one involves a pathogen and a host. The pathogen can be a bacterium, a virus, a fungus, a parasite, or a prion (a protein particle).
What is the best way to break the chain of infection?

Ways to break the Chain of Infection:
- elimination of sources of infection (reservoirs)
- appropriate handling and disposal of body secretions vomitus, faeces, sputum, blood and body fluids.
- appropriate handling of contaminated items, segregation of waste categories and disposal.
What is the weakest link in the chain of infection?
The means of transmission is the weakest link in the chain of infection, and it is the only link we can hope to eliminate entirely. Most infection control efforts are aimed at preventing the transport of germs from the reservoir to the susceptible host.
Who discovered the chain of infection?
Louis Pasteur (120) had established the immunological theory as early as 1881, well before the first formulation of the genetic theory, which followed the discovery of asymptomatic infections in the first two decades of the twentieth century (63, 123).

What are the 6 parts of the 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.
How does breaking the chain of infection Minimises the spread of infection?
Certain conditions must be met in order for a microbe or infectious disease to be spread from person to person. This process, called the chain of infection, can only occur when all six links in the chain are intact. By breaking this chain at any of the links, the spread of infection is stopped.
How does hand washing break the chain of infection?

The most effective method of hand hygiene is soap and water. Washing your hands with soap and running water loosens, dilutes and flushes off dirt and germs.
