3. Chain 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. Links in the chain Description: The chain of infection has 3 main parts. A reservoir such as a human and an agent such as an amoeba. The mode of transmission can include direct contact, droplets, a vector such as a mosquito, a vehicle such as food, or the airborne route. The susceptible host has multiple portals of entry such as the mouth or a syringe For an infection to develop, each link of the chain must be connected. Breaking any link of the chain can stop the transmission of infection! CHAIN OF INFECTION Infectious Disease Reservoir Portal of Exit Mode of Transmission Susceptible Host Portal of Entry .

  1. Therefore, to prevent germs from infecting more people, we must break the chain of infection. No matter the germ, there are six points at which the chain can be broken and a germ can be stopped from infecting another person. The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and.

The 6 links in the chain of infection. 1. The pathogen. The first link in the chain of infection is the infectious agent or pathogen which can take the form of: Viruses - such as Influenza A, shingles and Hepatitis. Bacteria - including Lyme disease and Leptospirosis. Fungi - for example Candidiasis and Aspergillosis chain of infection. If this 'chain' is broken at any stage, the infection cannot spread and becomes contained.

As healthcare professionals, it is essential to discuss this outbreak briefly with patients. We can empower the patient with common tools to break the chain of infection, such as washing hands often, covering the mouth properly with the arm when sneezing, and identifying proper hand sanitizers to use Vertebrates inevitably die of infection if they are unable to make antibodies. Antibodies defend us against infection by binding to viruses and microbial toxins, thereby inactivating them (see Figure 24-2). The binding of antibodies to invading pathogens also recruits various types of white blood cells and a system of blood proteins, collectively called complement (discussed in Chapter 25) The fecal-oral route (also called the oral-fecal route or orofecal route) describes a particular route of transmission of a disease wherein pathogens in fecal particles pass from one person to the mouth of another person. Main causes of fecal-oral disease transmission include lack of adequate sanitation (leading to open defecation), and poor hygiene practices

The virus is primarily spread when an uninfected (and unvaccinated) person ingests food or water that is contaminated with the faeces of an infected person. The disease is closely associated with unsafe water or food, inadequate sanitation, poor personal hygiene and oral-anal. Each L chain consists of one variable domain, VL, and one constant domain, CL. The H chains consist of a variable domain, VH, and three constant domains CH1, CH2 and CH3. Each heavy chain has about twice the number of amino acids and molecular weight (~50,000) as each light chain (~25,000), resulting in a total immunoglobulin monomer molecular.
