See Figure 4.1 [1] for an illustration of the chain of infection. If any “link” in the chain of infection is removed or neutralized, transmission of infection will not occur. Health care workers must understand how an infectious agent spreads via the chain of transmission so they can break the chain and prevent the transmission of ...

Dec 7, 2023 · The chain of infection consists of several key components, including the virus or bacteria as the causative agent, the host, and the vector. Understanding the transmission of diseases is essential in preventing and controlling their spread. The virus or bacteria serves as the primary causative agent in the chain of infection.
Dec 7, 2023 · The chain of infection is composed of six different links: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. Understanding each link in the chain is critical for preventing the spread of infections and protecting public health. The infectious agent is the microorganism that causes the ...
Sep 27, 2020 · This action is not available. Chain of infection. This model explains the spread of a communicable disease from one host (or person) to another. The basic idea represented in the chain of infection is that individuals can break the chain (reduce the risk) at any point; thus the spread of the disease can be stopped.
An infection occurs when harmful germs (microorganisms) enter the body, multiply and cause disease. The chain of infection refers to how germs spread (Figure 1.1). When an infection occurs, three things are involved: the source – the germs and where they live. spread – how the germs get out of one person and move to a new person.
How Infection Works. There is a close connection between microbes and humans. Experts believe about half of all human DNA originated from viruses that infected and embedded their nucleic acid in our ancestors’ egg and sperm cells. Microbes occupy all of our body surfaces, including the skin, gut, and mucous membranes.

The body’s extreme response to widespread infection, called sepsis, is the outcome of an inappropriate immune response to an infection that results in function failure in multiple organ systems within the body. Severe complications to organs may occur if untreated, which can ultimately lead to death.
