1.1
Bacteria are one-celled organisms visible only with a microscope. They are capable of multiplying by themselves, as they have the power to divide.
Viruses are coated genetic material. They can't multiply on their own; viruses consist of genetic materials which are protected by protein. They latch on to other cells and invade them.
Fungi are multi-celled organisms that has no chlorophil.it is neither plant nor animal. Absorbs nutrients from their surroundings.
Parasites are plants or animals that derive benefit from the metabolism of other plants or animals at the expense of the host and without providing some benefit to the host in return.
1.2
Common illnesses and infections caused by bacteria, viruses, fungi and parasites are
Pneumonia, ear infection, food poisoning, tuberculosis, MRSA, malaria, tonsillitis, athlete’s foot, yeast infections, coughs and colds, diareaha and vomiting.
1.3
Infection
Infection is a process in which bacteria, viruses, fungi or other organisms enter the body, attach to cells, and multiply.
Colonisation
Is when one or more species populate an area. Settlement of a colony.
1.4
Systemic infection
Is when a virus or bacteria spreads throughout the whole body through the blood causing infection in more than one area.
Localised infection
Localised means the infection is restricted to one small area or region. A localised infection can spread and become systemic.
1.5
Poor practices that may lead to the spread of infection
Not washing hands or not washing them correctly.
Not using ppe
Not bagging waste products
2.1
Conditions needed for the growth of micro-organisms are food to survive, warmth, moisture, air and time.
2.2
Infective agents may enter the body through many routes i.e. Mouth, lungs, cuts, skin contact, eyes, ears, urinary tract, anus, nose, bodily fluids.
2.3
Common sources of infection are food, water, unhygienic area or equipment and sick people.
2.4
Infective agents can be...
