Chain Of Infection Overview Figure 4.1 chain of infection. the links in the chain of infection include infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host [2]: infectious agent: microorganisms, such as bacteria, viruses, fungi, or parasites, that can cause infectious disease. reservoir: the host in which infectious. The chain of infection (a.k.a. chain of transmission). one way to visualize the transmission of an infectious agent though a population is through the interconnectedness of six elements linked in a chain. public health control and prevention efforts focus on breaking one or more links of the chain in order to stop disease spread.
Chain Of Infection Infographic Cornelia Svela 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. Section 10: chain of infection. as described above, the traditional epidemiologic triad model holds that infectious diseases result from the interaction of agent, host, and environment. more specifically, transmission occurs when the agent leaves its reservoir or host through a portal of exit, is conveyed by some mode of transmission, and. What is a chain of infection? learn the definition, order, and cycle of the chain of infection. lesson summary. an illness begins with the chain of infection. the first step in this chain is a. The chain of components has six sections. they include: microorganisms: disease producing, also called pathogens. virus, parasite, fungus, bacterium. risk factors: virulence, pathogenicity, ability to enter host. reservoir source: environment habitat where a pathogen can live and multiply.
