Preventing Disease Spread Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

It stops people swallowing pathogens that live in dirty water, such as bacteria that cause diarrhoea.

Give one way good food hygiene can reduce the spread of disease.

Cooking food fully kills pathogens that could make you ill.

How can covering your mouth and nose when you cough or sneeze reduce disease spread?

It traps droplets that contain pathogens, so they cannot move through the air to other people.

It is an animal, such as a mosquito, that carries pathogens from one host to another.

How can controlling vectors, like mosquitoes, help prevent disease spread?

Killing vectors or stopping them biting people stops the pathogens they carry from spreading.

Vaccinated people are less likely to get ill and pass on the pathogen, so fewer people become infected.
