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 enters through an appropriate portal of entry to infect a susceptible host. This sequence is sometimes called the chain of infection. Figure 1.19 Chain of Infection Image

The outbreak of infection can be fatal if care is not taken; for instance an outbreak of MRSA that can be resistant to most antibiotics can be fatal. The outbreak of an infection has consequences for individuals‚ staff and the organisation. It can cause ill health to all concerned and it can also impact emotionally because people that acquire infection relate it to being dirty and some infections may require people to be isolated from others for a period of time. The organisation could lose money

Practice for Infection Prevention I am a Medical Assistant in ambulatory care. Today‚ a patient visited our office with symptoms of Urinary Tract Infection (UTI). I check in the patient by verifying his name‚ date of birth and address congruent with his photo ID and his insurance card. When front office transit the patient’s file over to the back office‚ I pick up the patient’s chart and bring the patient to the exam room to measure his vital sign. Before proceeding‚ I record chief complaints and

certain diseases. The environment plays an important role as well. Children in day care centers and in school pass infections around and then take them home and pass them to siblings and parents. This is a cycle that is difficult to break. Children also don’t always practice good hygiene and that makes them both susceptible to as well as good transmitters of disease. Many human infections are caused by either bacteria or viruses. Immunisation is available to prevent many important bacterial diseases

The Upper Paleolithic was a period of great transition in the world. This was the height of technical sophistication during the Old Stone Age. The Neanderthals in Europe became edged out and disappeared by 33‚000 years ago‚ and modern humans began to have the world to themselves. Naturally‚ this will lead to what many have called a time of “creative explosion”. In the Upper Paleolithic‚ culture emerged as a stronger force than biology. Humans no longer needed to use their physical strength; tools

INFECTION An infection is the colonization of a hostorganism by parasitespecies. Infecting parasites seek to use the host’s resources to reproduce‚ often resulting in disease. Colloquially‚ infections are usually considered to be caused by microscopic organisms or microparasites like viruses‚ prions‚ bacteria‚ and viroids‚ though larger organisms like macroparasites and fungi can also infect. Hosts normally fight infections themselves via their immune system. Mammalian hosts react to infections

Cross Infection Definition Cross infection is the physical movement or transfer of harmful bacteria from one person‚ object‚ or place to another‚ or from one part of the body to another (such as touching a staph-infected hand to the eye). When this cross infection occurs in a hospital or long-term care facility it is called a nosocomial infection. Community acquired infections are those contracted anywhere except a hospital or long-term care facility. Description Cross infection accounts for
