Unit 12BM:
Direct contact:
These diseases are transmitted from person to person. To prevent the spread of these
diseases the first step would be to avoid close contacts with those affected by the disease. If
you have come into contact with someone infected with a disease, for example you shake
an infected person’s hand, you should wash your hands afterwards with antibacterial soap
or use hand sanitizer to ensure that all the germs have been killed.
Droplet and Airborne:
To stop the spread of these diseases whether you are infected with them or not when you
sneeze or cough you should do so into a certain space for example into a tissue or the crook
of your arm. This stops the droplets from the sneezing/coughing from spreading further
(into the air for someone else to be infected). Another method of preventing airborne
disease is wearing a face covering to prohibit the entering of hazardous particles through
the nose or mouth.
Indirect contact:
To stop the spread of these diseases, if you are infected or someone close to you is infected
(e.g., in the same class) you should always sanitize the space you are working in or where
you have been with disinfectant or surface wipes. You should also wash your hands if you
and the infected person have touched the same objects/ surfaces to limit the possibility of
you catching the disease.
Vector:
These diseases are spread through insects. To stop the spread of these diseases you could
use preventative measures such as, using insect repellent spray or sleeping under a net to
prevent mosquitoes from landing on you. There are also insect repellent creams that go on
the skin.
Vehicle:
To prevent these diseases from spreading you could make sure you do not share food or
drinks with others who may be infected. Ensuring a clean water supply will stop the spread
through contaminated water.
