Causes and spread of infection

Final result 1 - Understand the factors behind infection

one particular - Determine the differences among bacteria, viruses, fungi and parasites

Bacteria - Bacteria are microorganisms made up of simply 1 cellular. They are in a position of growing by themselves, because they have the power to divide. Bacteria exist just about everywhere, inside and our bodies. Many of them are totally harmless and a few of them are very beneficial. But some bacterias can cause illnesses, either mainly because they end up in the wrong put in place the body or just because they are 'designed' to occupy us.

Viruses - Viruses are too up-and-coming small to be seen by the naked eye. They can't multiply on their own, therefore they have to occupy a 'host' cell and take over it is machinery to become able to produce more disease particles. They may be capable of latching upon cells and having inside them.

Fungi - Any of several unicellular, multicellular, or syncytial spore-producing microorganisms feeding on organic subject, including conforms, yeast, mushrooms, and toadstools can be possibly moulds or yeasts. One common yeast infection is usually thrush, due to Candida albicans.

Parasites - A vermine is a great organism that lives in or on one more organism (the host), which in turn damages the host in some manner, plus fails to compensate for this damaging by also declining to help the host to an appreciable magnitude. More directly, the term parasite is often used to describe parasitic protozoa, helminths (worms) and arthropods.

2 - Determine common health problems and infections caused by bacteria, viruses, fungi and organisms.

3 -- Describe precisely what is meant by simply " infection" and " colonization".

Attacks - Infection is brought on by the breach of foreign cells, just like bacteria in humans, that cause harm to the host organism. Generally, the host affected person is considered " colonized" by simply cells that don't belong to it. These kinds of foreign cells must be harmful to the host organism to ensure the colonization to be regarded an infection.

Colonization - However often mistake the two terms, colonization is not the same as contamination. Colonization occurs when micro-organisms inhabit a certain body site (such because the skin) but avoid cause signs or symptoms of infection. Colonized pathogens have the potential to cause disease if that they spread to another site about the same patient in order to another person. Person-to-person transmission is a major path of colonization within health-related facilities. Even though a person can turn into infected the moment a pathogen invades, in many cases, colonization (without signs and symptoms of infection) happens before disease occurs.

four - Describe what is intended by " systemic infection” and " localized infection".

A systemic infection is one that influences the whole body, probably traveling in lymph or blood vessels. This is unlike a local contamination which only affects the region where the infection entered.

Localized infection explains what occurs when almost all infected cells is preserved within the one area. If afflicted tissue shattered away from the initial site of infection and travelled to various other body parts, it will no longer be localized.

5 -- Identify poor practices which may lead to the spread of infection.

-- Poor staff training in simple infection control

-- Not using the correct PPE

- Poor infection control techniques and procedures

- Certainly not following policy and treatment

- Not really washing hands correctly

- Not washing hands by any means

- Not enough sanitization

-- Incorrect storage of waste materials

Outcome 2 - Understand the transmission of infection

you - Describe the conditions necessary for the growth of micro-organisms
