Epidemiology

Epidemiology is the branch of medical science that deals with the transmission and control of disease. Epidemiology is the study of health events, health characteristics and health determinant patterns in a population. It is a cornerstone method of public health research and its major areas of work include outbreak investigation; disease surveillance and screening; biomonitoring; and comparisons of treatment effects such as in clinical trials.

510 Questions
Epidemiology

What are the key elements in epidemiology?

The key elements are:

an understanding of disease processes (like what a vector is),

knowledge of data or information available (like numnber of infections),

knowing what a Geographic Information Systems (GIS) is (to analyze patterns)

and an understanding of social sciences (that can indicate risk factors).

I have not taken courses in this (yet) but I work with MPHs and do data and GIS work for them.

What is the difference between clinical medicine and epidemiology?

physician concern with disesase in the individual patient where as the epidemiologist concern with disease pattern in the entire population

Epidemiology

What is epidemiology?

epidemiology is ofcourse, the study of disease and ewpidemiologists often study the diseases in a certain location, area, of community.

What is the difference between biostatistics and epidemiology?

Biostatistics is application of statistical methods in biology, medicine and public health. Epidemiology is the study of patterns of health and illness and associated factors at the population level.

What are the main features of epidemiology?

well I have the idea that first in science of medicine there are prefixes and suffixes to the meaning of their words.

Here the suffix ology means , the study of something. The second part or rather the pre-fix is close to the word "epidemic" . I would venture to say this is asking: what is done in the study of epidemics. I would think to keep a spread of a disease to the masses,

first there might be quarantine for the affected. Perhaps even those possibly affected.

If there is already a vaccine for the illness , the health departments would give free shots until the supply ran out for those not yet positive with the illness.

The cause of the epidemic would be important to know so that scientist could test the possible cause for the massive outbrake. We would want to know...how it travels,spreads, what we should stay clear of ..... for example any thing that might give the illness opportunity to gain power or strength. As soon as we knew more about the cause and its affects on the people the government would hopefully take the measures needed to at least narrow the geographics down and confine it in that space . I think this would help the scientist know how much time they have to discover a vaccine if there isn't one, possibly a cure ,but the ability to give the knowledge the public would need to stay alive would be crucial in keeping the spread minimal. Tracking of the people infected, their families, their recent activities and travels. Any thing that might have occured in their life that was not in their usual day to day activities.Also tracking of other things that have commonalities in the specifically defined area affected.

There I do not know if I am correct totally or not at all. So if this is a ? from someone needing help I suggest a doctor visit immediately or even the health department. Can't think of one more thing. I'm surprised I came up with that many ideas not being a scientific person.

If any one knows if I'm correct or even incorrect ,please write it. I want to learn what is really done.

What is the role of statistics in epidemiology?

The primary role of statistics in epidemiology is to make conclusions about a population of interest when data is only available from a sample. Statistics accounts for the uncertainty.

In epidemiological datasets there are usually measured observations of an occurance of a disease as well as measured indicators of exposure. An epidemiologist may for example be interested in whether exposure (e.g. smoking) increases the risk of disease (e.g. cancer). Information on smoking however may not be available for all people in the population of interest because of limited resources, so an epidemiologist would have to consider taking a sample. An epidemiologist would use a random sample in order to use statistics to to make inference about the association between smoking and cancer in the population. The role of statistics is to determine whether any association that is observed in the random sample is actually a real one. In most cases there will be some association even if it is very small. The role of the statistician is to determine if the association is different than what would occur by chance.

Epidemiology

Why is epidemiology fundamental to the practice of public health?

Epidemiology is considered as basic science of public health. It is study of health related events in population. It takes into account the pattern & rate of risk of disease in the population. So it is fundamental to the practice of public health.

Epidemiology

What is the importance of epidemiology?

Epidemiology is the study of the spread of disease. It helps scientists to predict how far a disease will spread, how much damage it may do, and plan treatment, the creation of vaccines, and so forth. The current preparations for swine flu were a result of epidemiological studies.

The science which studies the causes and controlling epidemic diseases.

Epidemiology

What is meant by sensitivity in epidemiology?

The ability of lab test to identify correctly those individuals who have disease.

It means that individual having a disease with positive test.

What is an epidemiology model?

This is a model this can be used to predict or track the development of an epidemic.

It can often be referred to as the SIR model. Susceptible, Infected, Recovery.

A population is susceptible to a disease, it can then become infected once it catches the disease and then recovers. It may be there is a positive feedback into the susceptible category if the recovered people cannot develop immunity.

Various external factors control the risk of the susceptible populous e.g. exposure, health diet etc. The Infected rate depends upon exposure, type of disease, ease of infection etc. The recovery depends upon the disease. In the most extreme cases of death the populous for mathematical purposes is removed from the recovery category.

If you know your population e.g a school. Then you can enter hypothetical illnesses such as mumps into the model to see how quickly the disease would spread in the school. This can allow you to develop strategies to reduce infection and promote recovery e.g. isolation or washing hands.

How long does it take to get a Ph.D in Epidemiology?

A Ph.D. in a biological science is the minimum education required for most prospective medical scientists, except epidemiologists. However, some medical scientists pursue medical degrees to perform clinical work. Epidemiologists typically need at least a master's degree in public health, but some work requires a Ph.D. or medical degree. A period of postdoctoral work in the laboratory of a senior researcher is becoming increasingly common for medical scientists.

What are the advantages and disadvantages of case control studies?

Advantages

Less expensive than other analytic studies

Less time consuming

Good for rare diseases

Disadvantages - Bias

Recall bias - people who have had the disease and better able to determine their exposure

Information bias- the difference between the measurment of each group

Selection bias- the difference between how the groups wre selected.

How epidemiology data improve health status in Australia?

By studying the patterns of health and illness and associated factors at the population as a whole, risks, causes etc can be identified and prevention/action can be implemented.

But with research today, this is already in place and has been for many years.

Heart foundation, smoking/anti smoking, alcohol affects, diabetes, etc etc, these are based on what has been studied, causes found and action has been taken and people are aware of these.

But knowing what is good/bad, knowing the risks, knowing what decreases health or what increases illness will not deter an individual/population. People do what they like as they are entitled to, people will smoke, people will drink, people will have high cholesterol from poor diets, people will continue high fat/high sugar diets, no exercise etc etc even though they know it is not advised for their health.

Just like any country and it's people, not just us Aussies.

How do you calculate average duration in epidemiology?

P/1-P where 1-P is the prevalence odds. This is true for prevalence values that are bigger.

Prevalence=Incidence rate x Duration (true for small prevalences)
