Certain conditions must be met in order for a microbe or infectious disease to be spread from person to person. 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. Limiting antimicrobial exposure to patients through antimicrobial stewardship is a common strategy. The droplets will rapidly fall on nearby surfaces (tables, door knobs, telephones, elevator buttons, etc. a process for how to operate in a post-coronavirus environment. Examples of disease spreading from animals or insects to humans include: Environmental reservoirs harbor many infectious diseases.

Bacteria - including Lyme disease and Leptospirosis. Write the letter (e.g. Understanding how the infection is spread is essential to our efforts to prevent and contain its spread, especially when there is no definitive treatment available. 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. If one or more links are Chain of Infection. 30 seconds. A host then enters the space where the pathogen is suspended and has the potential to become infected.

Chain of infection is a process of infection that begins when an agent leave its reservoir through portal of exit & is conveyed by mode of transmission then enters through an appropriate portal of entry to infect a susceptible host. If they touch their nose or mouth with contaminated hands, they can get infected. Infectious agent (Pathogen) This is any micro-organism that causes infection such as MRSA, Clostridium difficile or influenza. This process, called the chain of infection, can only occur when all six links in the chain are intact.
