A subsidiary aspect of infection control involves preventing the spread of antimicrobial-resistant organisms such as MRSA. This in turn connects to the discipline of antimicrobial stewardship —limiting the use of antimicrobials to necessary cases, as increased usage inevitably results in the selection and dissemination of resistant organisms.
Preventing the spread of diseases means breaking the chain of infection transmission so that infection cannot spread. "Targeted hygiene" is based on identifying the routes of pathogen spread in the home and introducing hygiene practices at critical times to break the chain of infection. [11]
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
In epidemiology, force of infection (denoted ) is the rate at which susceptible individuals acquire an infectious disease. [1] Because it takes account of susceptibility it can be used to compare the rate of transmission between different groups of the population for the same infectious disease, or even between different infectious diseases.
Transmissibility is the probability of an infection, given a contact between an infected host and a noninfected host. [8] Community transmission means that the source of infection for the spread of an illness is unknown or a link in terms of contacts between patients and other people is missing. It refers to the difficulty in grasping the ...
Chain of infection; the chain of events that lead to infection. There is a general chain of events that applies to infections, sometimes called the chain of infection [14] or transmission chain. The chain of events involves several steps – which include the infectious agent, reservoir, entering a susceptible host, exit and transmission to new ...
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
Food safety (or food hygiene) is used as a scientific method/discipline describing handling, preparation, and storage of food in ways that prevent foodborne illness.The occurrence of two or more cases of a similar illness resulting from the ingestion of a common food is known as a food-borne disease outbreak.
