Infectious diseases are illnesses caused by the spread of microorganisms (bacteria, viruses, fungi or parasites) or prions to humans from other humans, animals or the environment, including food and water.
To minimise the risk of spread of infection, all blood and body substances should be treated as potentially infectious. Find standard precaution techniques used in handling these substances on the Handling blood and other body substances page.
Exclusion from childcare, preschool, school and work
The spread of certain infectious diseases can be reduced by excluding a person, known to be infectious, from contact with others who are at risk of catching the infection.
