1.4 Diseases
Controlling the spread of diseases
Diseases can be spread in food, water and air, and by body contact.
There are different ways we can help to control the spread of diseases.
Good hygiene
Many diseases are spread in food, water and body fluids. We can help prevent the
diseases from spreading by good hygiene. This means keeping ourselves and the
things around us clean.
These are some of the things we can do:
• Wash our hands with soap and water before eating or working with food and after
going to the toilet. Also drying our hands well on a clean towel.
• Wash our hands after handling animals, cleaning up animal waste or gardening.
• Wash raw unpeeled fruits and vegetables before eating them.
• Keep food covered.
• Do not leave food at room temperature, especially when the weather is hot, as bacteria
and fungi grow faster when it is warm.
• Keep the kitchen, toilet and surroundings clean.
• Wash knives and working surfaces in the kitchen with hot soapy water after using them.
• Only drink safe, clean water. Boil water from rivers or reservoirs, or use water that has
been chemically treated at water treatment plants to make it safe.
• Do not use rivers or other bodies of water as a toilet.
• Cover your nose and mouth with a tissue when you cough or sneeze.
If you do not have a tissue, cough or sneeze into your elbow,
not your hand.
• Keep wounds covered with a plaster and do not
touch other people’s open wounds.
