Unit 4222 265 Finishedprint For 5th Feb
Unit 4222-265 – understand the causes of infection
Outcome 1 - understand the causes of infection
1. Identify the differences between bacteria, viruses, fungi and parasites.
Bacteria – is a single cell micro-organism that gets its nutrition from its surroundings and can only be seen under a microscope
Viruses - are disease producing agents far smaller than bacteria. They are enclosed in a protein coating which makes them more difficult to destroy.
Parasites – an organism that feeds and is dependant of its host.
Fungi - are multi-cellular organisms.
2. Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites.
Bacteria – Lyme disease, Tuberculosis, tetanus.
Viruses – polio, Norovirus, common cold, flu, chicken pox
Fungi – athletes foot, oral thrush
Parasites - worms, ticks, lice, mites
3. Describe what is meant by infections and colonisation.
Infection – is an invasion to the body tissues from a disease.
Colonisation – occurs when any one or more species populate a specific area.
4. Explain what is meant by systemic infection and localised infection.
Systemic infection affects a number of organs, tissues or affects the whole body for example type 2 diabetes, aids and hyper tension and Localised infections are confined to one organ system or area in the body for example abscesses, boils or sprains.
5. Identify poor practices that may lead to the spread of infection.
Not wearing personal protective equipment such as disposable gloves, disposable aprons, washing hands and disposing of clinical waste in the correct way can cause the spread of infection wearing the correct equipment shoud prevent infections and diseases from spreading.
Outcome - 2 understand the transmission of infection
1. Explain the conditions needed for the growth of micro-organisms.
The main requirements for the growth of micro organisms are time and moisture, some need oxygen and warmth to be able to grow properly.
2. Explain the ways an infective
