Differences between infectious and non-infectious disease
Lesson details
Learning outcome
I can describe some common infectious and non-infectious diseases and their causes.
Key learning points
- Infectious diseases can be passed from one organism to another.
- Infectious diseases are caused by pathogens including viruses and some bacteria.
- Some lifestyle factors are linked to non-infectious diseases.
- Non-infectious diseases cannot be passed from one organism to another.
Keywords
Infectious - Can be spread from organism to organism.
Disease - A persistent deviation from a person’s normal appearance, body function or behaviour.
Pathogen - A virus, bacterium or other microorganism that causes disease.
Viruses - Non-living infectious agents that can replicate inside a host cell.
Bacteria - Unicellular microorganisms that do not have a cell nucleus.
Common misconception
Non-infectious diseases such as heart disease can be passed from person to person.
Only infectious diseases caused by pathogens can spread from person to person.
Teacher tip
Coronary heart disease is when blood flow to the heart is restricted. A stroke is when blood flow to the brain is restricted. Cancer is when a cell in the body divides uncontrollably and forms a tumour. Type II diabetes is the lack of blood sugar control.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
