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

Plato was an Ancient Greek philosopher whose writings and theories have greatly influenced the development of Western philosophy. Perhaps his most famous theory is that of the Forms - pure ideas or concepts of what a THING is. It was Plato’s belief that as well as this world‚ the material world - or the world of Appearances‚ as he called it - there exists another dimension‚ where the true Forms of everything in the material world reside; Reality‚ or the realm of the Forms. A Form‚ by Plato’s reckoning

Hand washing is widely acknowledged to be the single most important activity for reducing the spread of infection‚ yet evidence suggests that many healthcare professionals do not use the correct technique. This means that areas of the hands can be missed. The author feels that this is crucial in preventing and controlling infection and this is why the particular

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

developing a computer model of the spread of an infectious disease‚ the student develops an understanding of the role of the infection rate and the removal rate on the spread of the disease. The Threshold Theorem of Epidemiology claims that the extent of spread of an epidemic can be predicted if three values are known: initial number of susceptible people (S(0))‚ the infection rate (K)‚ and the removal rate (by quarantine or cure) (Q). The extent of the spread of the epidemic is indicated by the percentage

Infection Control What causes people to get sick? How is disease spread from one person to another person? What can be done to stop the spread of infection and disease? As a health care worker‚ it is important to know the answers to these questions. When you understand what causes infection‚ you can learn how to prevent it. Infection control is a set of practices and procedures that will help to prevent the transmission of disease within a health care facility. Infectious and Communicable Diseases

Bacteria causes infections and can reproduce either inside or outside the body. Viruses are pieces of nucleic acid (DNA or RNA) wrapped in a thin coat of protein. Viruses need to be inside living cells to grow and reproduce. They do not survive long unless they are inside a living thing eg: person
