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.
Ways infectious diseases spread
Find out how infectious diseases can be spread, including links to information on how to avoid spread on the Ways infectious diseases spread page.
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.
Find the recommended minimum periods of exclusion from school, preschool and childcare centres for cases of, and contact with, infectious diseases on the Exclusion from childcare, preschool, school and work page.
