Bacterial and viral diseases in humans: Salmonella and influenza
Lesson details
Learning outcome
I can describe examples of common bacterial and viral diseases in humans, how they are spread, and ways to reduce the spread.
Key learning points
- Some, but not all, bacteria are pathogens that can cause communicable diseases in humans.
- Pathogenic bacteria produce toxins that damage living tissue and cause disease.
- Salmonella food poisoning as an example of a bacterial disease, how it is spread, and how the spread can be reduced.
- Viruses invade cells to reproduce where they cause damage to cells.
- Influenza as an example of a viral disease, how it is spread, and how the spread can be reduced.
Keywords
Bacteria - single celled prokaryote.
Pathogen - a micro-organism that causes disease.
Communicable disease - a disease that can be spread from person to person.
Toxin - a poison made by bacteria.
Virus - an infectious agent.
Common misconception
Viruses are alive.
Viruses do not carry out many of the life processes required for living organisms such as respiration and reproduction.
Teacher tip
David Vetter can be mentioned later whilst you discuss viral infections. He eventually died because the bone marrow he received was infected with a dormant virus. He had no immune system to remove the virus.
Equipment
None required.

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.
