Define the terms 'outbreak', 'endemic', and 'epidemic' in the context of communicable disease control.

Outbreak refers to an increase in the number of infections that is relatively localized in time and space. Endemic refers to the usual or expected persistent level of disease in a given area or community. Epidemic refers to a rise in case numbers above the background or expected rate of the disease in a community or region. Signup and view all the answers

How is pandemic strictly defined and how is it commonly applied in practice?

Pandemic is strictly defined as any epidemics that cross international boundaries and affect a large number of people worldwide. However, in practice, it is usually applied to infections that pose a serious risk to public health and cause severe illness with little population immunity. It does not include cyclical or seasonal infections like regular seasonal flu. Signup and view all the answers

What are the key concepts in communicable disease control?

The key concepts in communicable disease control include outbreaks and epidemics, which are defined as an increase in the number of infections that is relatively localized in time and space, the usual or expected persistent level of disease in a given area or community, and a rise in case numbers above the background or expected rate of the disease in a community or region.

What are the key elements of effective communication in outbreak management?

What is an infectious disease emergency?

An infectious disease emergency refers to events that involve biological agents/diseases and result in rapidly escalating case numbers and severe clinical disease. These events often present challenges in achieving effective community control. Signup and view all the answers

Which kinds of pathogens have the potential to cause infectious disease emergencies?

Pathogens such as viruses (e.g., pandemic influenza, coronaviruses, Ebola) and bacteria (e.g., bubonic plague, anthrax, cholera) have the potential to cause infectious disease emergencies. Signup and view all the answers

What are the impacts of pandemics and infectious disease emergencies on health and survival?

Pandemics and infectious disease emergencies pose major threats to population health in terms of morbidity (illness) and mortality (death). They can disproportionately affect vulnerable populations such as the very young, the elderly, and individuals with impaired immune systems or chronic diseases. Additionally, they can have significant mental health impacts and disrupt social and economic functioning. Signup and view all the answers

What is the concept of 'flattening the curve' in the context of COVID-19 and why is it important?

'Flattening the curve' refers to reducing the number of active cases at any given time in order to give both health services and other essential services time to prepare and respond, without becoming overwhelmed. It is important because it aims to avoid a large spike of cases that cannot be managed by the health system and to reduce the case numbers to a lower level over a longer time to keep the cases below the level of maximum health system capacity.

What is the concept of 'defence in depth' or 'layered interventions' in the context of COVID-19 and why are they more effective than single measures?

'Defence in depth' or 'layered interventions' refer to combining multiple measures to reduce the risk of infection. They are more effective than single measures because each measure may have 'holes' or limitations, but when multiple measures are combined, the holes are less likely to align and the pathogen will not be able to slip through. Combining measures may increase protection but will inevitably increase their overall cost. Signup and view all the answers

What are some recommended non-pharmaceutical public health measures to reduce transmission of COVID-19?

Some recommended non-pharmaceutical public health measures to reduce transmission of COVID-19 include hand hygiene, respiratory etiquette, face masks for symptomatic individuals, voluntary isolation of ill individuals, surface and object cleaning, health advice for travelers, avoiding crowding, school closures and other measures, and workplace closures and measures.

What is the purpose of contact tracing in the context of infectious disease control?

The purpose of contact tracing is to identify and locate individuals who have been in close contact with an infected person in order to assess their risk of infection, provide necessary support and guidance, and prevent further transmission of the disease. Signup and view all the answers
