Triggers and spread of contamination

outcome 1- to understand the causes of infections

recognize the differences between bacteria, infections, fungi and parasites.

1) Bacteria is a organism that is present in the majority of habitats, as well as human physiques and other living organisms just like plants and animals. Bacteria multiplies by simply its do it yourself to progress and spread. In contrast to other infections such as malware, fungi or perhaps parasites bacteria is not at all times harmful actually in many cases bacterias can be useful to the living creatures, habitats or perhaps plants it infects. Viruses are a little infectious agent that can only multiply inside the cells of living organisms although as opposed to bacteria, disease and parasites viruses are generally not living organisms. Viruses can easily infect virtually any living organism such as humans, plants and animals. Malware multiply by spreading by organism to organism one example is viruses could be spread by human to human by coughing or perhaps sneezing. Fungi a disease is a member of a huge group of eukaryotic organisms therefore each of the cellular material contain membranes. Fungi can be identified through mushrooms, toadstools and candida. Common candida that are throughout the human body happen to be infections including thrush which is often overcome with a course of anti-biotics. parasites will be small creatures which depend on other living organisms to outlive such as headlice depend on blood from humans in order to make it through and replicate. Bacteria and viruses can both end up being parasites.

2) identify common illnesses and infections due to bacteria, fungus, viruses and parasites. bacteria| Fungi| viruses| Parasites


ear infections




whooping cough| thrush

ring worm

athletes foot| aids





| headlice




3) Explain what is supposed by infection and colonisation.

Infection is a word which is often used to describe when organism's bodily tissues are damaged or infected by organisms growing and causing harm to the cells by the harmful toxins that they generate or the destruction they cause. Infections can be caused by organisms, viruses and fungi. Colonisation is a term used to explain when a infection is found in the body which cause discomfort or have virtually any signs or symptoms. this means that bacteria is present within the surface such as skin, mouth, intestines or perhaps airway.

4) Explain precisely what is meant by the term systemic infection and localised illness. Systemic infection

A systemic contamination is the consequence of a malware or can happen when bacterias enters your body through disease, the blood stream is the most effected characteristic at this time infection due to this the symptoms spread to the entire of the body. When the disease is pass on throughout the physique pathogen is passed through the entire body, which is anything that can cause a disease, humans come into contact with pathogens every day and in most cases the defense systems happen to be strong enough to fight pathogens off. If the pathogen can be passed through the entire body bacterial toxins are developed which is the reason for systemic attacks. The most common kind of these infections are the common cold and flu's. When a person is affected by a systemic infection they are going to more than likely experience the feeling of aches, nausea and weakness. Localised infection

A nearby infection is known as a infection which usually only effects only one portion of the body and occurs on the outer surface of the physique which as a result of this means that the infection does not your bloodstream. Localized infections could be only slight infections such as a cut on the knee. 5) Identify poor practices which may lead to the spread of your infection. Poor practice can result in the distributed and cause of infections. Everyone on a daily basis is open to get and distributed infections, this can be by taking portion in poor practice. Poor practice could possibly be poor hygiene which means -not washing your hands after toileting

-not putting on PPE
