Causes And Spread Of Infection Unit 265
Unit 265 – Causes and Spread of Infection
1. Identify the differences between bacteria, viruses, fungi and parasites.
Bacteria is something that we need some of, it needs a warmth, moisture, time and food in order to multiply, which in the right conditions they multiply quickly.
Viruses need a living host in order to survive, they don’t respond to antibiotics and new strains of virus are developing all the time.
Fungi are moulds and yeasts, they need a warm and damp environment to survive, much like bacteria.
Parasites feed off the host it’s inhabiting, it uses the nourishment from the flesh to survive.
2. Identify common illnesses and infections caused by bacteria, viruses, fungi and parasites
The condition is:
Description of illness:
Is it Bacteria, Viruses, Fungi, or Parasite infections?
Verruca
It can be spread in swimming baths, or communal bathrooms

Painful stiff neck, and dislike of bright lights
Virus
Head lice
Nits may be seen
Parasite
MRSA

Bacteria
Flu
Sneezing and coughing
Virus
Macular Rash

Bacteria
3. Describe what is meant by ‘infection’ and ‘colonisation.’
Colonisation is when a microbe finds itself a host and a susceptible environment (for example; skin or an object) and then multiplies. Not necessarily threatening, but you then become the carrier.
Infection is when normal functioning of the body is disrupted, it can be for a short period of time, but in more serious cases it can be for a prolonged amount of time.
4. Explain what is meant by ‘systemic infection’ and ‘localised infection.’
A systematic infection is when signs and symptoms affect the whole of the body, and you may have more than one symptom i.e. aching
