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

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

UNIT 22 INFECTION CONTROL OUTCOME 1 UNDERSTAND THE CAUSES OF INFECTION 1.1 Bacteria are one celled micro-organisms that get their nutrients fro their environment to live eg: The human body. 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

Causes and spread of infection Micro-organisms that cause infections are known as pathogens. They may be classified as follows: Bacteria: minute organisms about one-thousandth to five-thousandths of a millimetre in diameter. They are susceptible to a greater or lesser extent to antibiotics. Viruses: much smaller than bacteria and although they may survive outside the body for a time they can only grow inside cells of the body. Viruses are not susceptible to antibiotics‚ but there are a few

Causes and Spread of infection Q 1.1 - Identify the differences between: bacteria‚ viruses‚ fungi and parasites. * Bacteria are unicellular‚ prokaryotic microorganism found almost in all kinds of habits. Some bacteria are beneficial like those involved in nitrogen fixation and some pathogenic‚ which cause diseases. * Viruses are unicellular‚ tiny organisms which is mostly composed of DNA (DeoxyriboNucleic Acid) and protein.

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

Unit 008; Causes and spread of infections. Outcome 1. Understand the cause of infection: 1) Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and uses the cells apparatus for reproduction. Fungi – it is a multi-celled living organism. Parasites – they are types of living plants and animals that derive benefit
