What is control measures that interrupt transmission?Show answer
Each control measure works by breaking a step in transmission.
What is matching the measure to the disease?Show answer
The best control depends on how the disease spreads. A droplet-spread respiratory disease is controlled by isolation, distancing and masks; a waterborne disease by clean water and sanitation; a vector-borne disease by controlling the vector. Choosing measures that target the actual transmission route is what makes control effective.
What is biosecurity in Australia?Show answer
Australia places strong emphasis on biosecurity because its isolation has kept out many diseases and pests found elsewhere. Strict controls at airports and ports, and quarantine of plants, animals and produce, aim to stop new pathogens entering. This protects both human health and the agricultural industries that depend on disease-free crops and livestock.
