What are the three principles of outbreak management?

During the outbreak management it may be necessary to take the following measures: quarantine (isolate a person until he or she is no longer infectious, based on the disease definition), isolation of contacts, and surveillance (passive and active).

What are the three key components of an outbreak investigation?

Once a decision is made to investigate an outbreak, three types of activities are generally involved-the epidemiologic investigation; the environmental investigation; and the interaction with the public, the press, and, in many instances, the legal system.

What are the principles of outbreak investigation?

The investigation includes the following steps: establishing the existence of the outbreak; defining the disease; finding cases; describing cases by time, place, and person characteristics; establishing a hypothesis related to the mode of occurrence; testing the hypotheses; conducting an environmental investigation; ...

What are the types of outbreak?

What is outbreak investigation and management?

The primary reason for conducting outbreak investigations is to identify the source in order to establish control and to institute measures that will prevent future episodes of disease. They are also sometimes undertaken to train new personnel or to learn more about the disease and its mechanisms for transmission.

What is infectious disease outbreak and its management?

Definition. An infectious disease is a viral, bacterial, parasitic, or fungal disorder that can be transmitted between people. An outbreak is an increased number of cases of a particular disease and can include epidemics and pandemics.

What is outbreak in epidemiology?

Generally outbreak means a “sudden occurrence,” while in the epidemiological sense an outbreak is defined as a sudden increase in the disease frequency, related to time, place, and observed population.

What are the three pieces of data used to characterize the outbreak of a disease or health situation?

The first question is answered with a description of the disease or health condition. “How much?” is expressed as counts or rates. The last three questions are assessed as patterns of these data in terms of time, place, and person.

How many steps comprise the investigation of an outbreak?

- Determine whether there is a clustering of cases, a cluster of cases of an outbreak-prone disease or a single case of a disease of international importance. - Review incidence in the past in the area of the outbreak.

What are the reasons for outbreak?

Water contamination is a key driver of disease outbreaks

In addition to water contamination, large outbreaks were most often associated with unusual weather patterns, changes in the abundance of vectors—carriers of disease like mosquitos or ticks—and sewage management.

What is the first step in outbreak management?

Verify the diagnosis and confirm the outbreak

The first step in an investigation is to determine whether the reported number of cases is unusual. Baseline surveillance data is a useful resource for making this decision.

Why do we manage outbreaks?

The purpose of outbreak management is to protect public health by identifying the source and implementing control measures to prevent further spread or recurrence of the infection.

How are outbreaks prevented?

High coverage of routine immunization is a critical firewall to prevent outbreaks from occurring, and vaccination of healthcare workers is especially critical to minimizing the spread of an emerging outbreak.

Which is the key principle of outbreak management?

The first key principle of outbreak management is to recognise an outbreak and establish that it actually exists. Then establishing a case definition for cases in the outbreak to assist with determining further infections. Precautions should commence as soon as the first resident shows symptoms of suspected infection.

What are the principles of treatment of disease?

Kill the cause of the disease: Use medicines that can kill the pathogens. Each microbe undergoes some specific biochemical life process which helps them to survive. The intake of certain drugs that block these biochemical processes can help in killing the microorganism causing the disease.

What are the 4 types of infections?

The four different categories of infectious agents are bacteria, viruses, fungi, and parasites. When studying these agents, researchers isolate them using certain characteristics: Size of the infectious agent.

What are principles of epidemiology?

Epidemiology is the study (scientific, systematic, data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (patient is community, individuals viewed collectively), and the application of (since ...

How do you identify a outbreak?

An outbreak with multiple sick people can be missed if they are spread out over a wide area. Outbreaks are detected by using public health surveillance methods, including PulseNet, formal reports of illnesses, and informal reports of illnesses.

How do you identify an outbreak?

To determine if there is an outbreak, the current number of new cases (incidence) can be compared with past levels of the same disease over a similar time period (base line level). If the number is unusually large or unexpected for the given place and time, an outbreak may be occurring.

What are the 5 steps of surveillance?

How do you write a outbreak report?

What are some examples of common source outbreak?

A common-source outbreak occurs when a group of people get sick after being exposed to a virus, bacteria, toxin, or other infectious agent from the same source. For example, a common-source outbreak happens when a group of people get sick after eating the same contaminated food at the same restaurant on the same day.
