What do you mean by epidemiology?
By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global).
Does epidemiology include etiology?
In medical parlance, etiology refers to the origin and cure of a certain disease. Epidemiology has a greater scope than etiology, as it is an ongoing process. Epidemiology involves the study of both determinants and distribution of disease, while etiology only attempts to expound on the determinants.

What are the 3 types of epidemiology?
The three major epidemiologic techniques are descriptive, analytic, and experimental. Although all three can be used in investigating the occurrence of disease, the method used most is descriptive epidemiology.
What is an example of epidemiology?
For example, comparing incidences of lung cancer in smokers and non-smokers showed a correlation between smoking and lung cancer. Epidemiologists also monitor trends over time. These longitudinal studies can identify emerging health issues and assess the effectiveness of control measures, such as vaccination.
Why is it important to study etiology?
In epidemiology etiology plays a vital role to understand the origin and cause of the disease. By studying the etiological conditions of infectious diseases, communicable and non-communicable diseases its cure and prevention can be intervened. Etiology refers to the many factors coming together to cause an illness.
Why is it important to know the etiology of a disease?
Etiology is not only disease specific but also person specific. While a particular cause may lead to a disease manifesting in an individual, a similar set of factors could lead to a different illness being manifested in another individual.
What does an epidemiologist study?
Often called “Disease Detectives”, epidemiologists search for the cause of disease, identify people who are at risk, determine how to control or stop the spread or prevent it from happening again. Physicians, veterinarians, scientists, and other health professionals often train to be “Disease Detectives”.
What are examples of etiology?
When a cause of a disease is determined, this is called its etiology. For example, the etiology of cholera is known to be a bacterium that contaminates food and drinking water in places with poor sanitation.

Opportunities for prevention arise at every stage in the process, and three main levels are described: primary, secondary, and tertiary.
What is the difference between causes and etiology?
Cause, also known as etiology (/iːtiˈɒlədʒi/) and aetiology, is the reason or origination of something. The word etiology is derived from the Greek αἰτιολογία, aitiologia, "giving a reason for" (αἰτία, aitia, "cause"; and -λογία, -logia).
What's the difference between pathology and epidemiology?
Pathology is at the cornerstone of cancer diagnosis, prognosis, prevention, and treatment as well as the molecular mechanisms of disease, while epidemiology provides insights into the burden of cancer, its causes and opportunities for prevention.
What is the difference between etiology and pathogenesis?
A disease may have one or more etiologies (initial causes, including agents, toxins, mutagens, drugs, allergens, trauma, or genetic mutations). A disease is expected to follow a particular series of events in its development (pathogenesis) and a particular clinical course (natural history).
Is etiology the same as risk factors?

What is epidemiology and etiology?
Epidemiology and etiology are terms used in medical parlance. One usually encounters case studies that start with, “Epidemiology and etiology of X disease .” The way the title is constructed gives one the impression that epidemiology and etiology are different from one another. However, people sometimes interchange these two terms, falsely assuming that they have the same meaning. Aside from sounding similar, their almost-synonymous usage in medical parlance fools people into thinking one can be substituted for the other; however, this is not the case.
How are epidemiologists and etiology related?
Epidemiologists utilize the scientific method through observation, experimentation, description, and analysis to pinpoint the cause of diseases and implement preventive measures. Etiology is similar to epidemiology in that it also deals with cause and effect. While epidemiology is used exclusively in the field of medicine, etiology can refer to the roots of a family tree, the story behind a name, or the history behind a place. Etiology is often utilized to explain how certain words in the English language were derived from Greek or Latin equivalents or how certain events led to the naming of places and structures. When used in medical parlance, etiology refers to the origins of a certain disease. When people ask how a certain disease occurs, when it was discovered, and who gave it its present name, they are referring to the etiology of that disease. Thus, even though epidemiology and etiology may seem the same, they are only closely related because they both deal with the nature of diseases.
What is the difference between epidemiology and etiology?
Epidemiologists use the scientific method to deal with new, unidentified diseases, while etiologists explain the nature of known diseases and how they can be prevented. Another difference between the two is that while etiology is content to expound on origin, cause, and effect, epidemiology is an ongoing study that keeps known diseases in check ...
Why is epidemiology important?
Epidemiology relies heavily on scientific methodology to isolate factors that affect the prevalence of diseases in a certain area. Once experts of epidemiology identify these factors, they can estimate the risks a certain population faces due to that particular disease.
What is the meaning of etiology?
When used in medical parlance, etiology refers to the origins of a certain disease. When people ask how a certain disease occurs, when it was discovered, and who gave it its present name, they are referring to the etiology of that disease.

What is the difference between epidemiology and etiology?
The difference between Epidemiology and Etiology is that Epidemiology refers to the deep study of both known and unknown diseases and then providing medical prescriptions to their patients. On the other hand, Etiology only studies the pre-discovered diseases and provides its solution and prevention ways.
What is Epidemiology?
Epidemiology is a term which is derived from the Greek word epidemic where Epi means among, and Demos means study population or group of people, and Logos means a scientific study. Therefore it is a study of disease patterns in the human population. This study is mainly done by physicians, health sector experts, etc.
What is the difference between an etiologist and an epidemiologist?
Epidemiologists first examine their patients deeply and find the root cause of the disease, then they provide medication for that. Whereas in the case of Etiologists, they only see the symptoms of the disease after that, they describe it to their patients and tell them about its preventive measures.
What is epidemiology in medicine?
Epidemiology is basically a medical term in which people study the prevention and outcomes of disease. The disease which they study can be old or known, or it can be new or undiscovered. Epidemiologists not only provide medication but also study the spread of disease and can prevent a pandemic from occurring.

Etiology is the study of the origin of a disease that has already occurred in the past, its name, its family tree, etc.
What is the study of the origin of a specific disease?
Etiology is also known as Aetiology. It is the study of the origin of a specific disease very deeply. The process in Etiology is not ongoing because Etilogists only study past diseases or the diseases which have already occurred in a particular set of the human population. This term is not only related to medical science. It is also related to physics, geography, and theology, etc.
How is etiology related to science?
Etiology is related to both medical as well as scientific terms because, in this, a person studies an already known disease, the origin of its name, and the places it has occurred before. Basically, it tells you about all the details of a disease that has occurred in the past and its causes as well as preventions.
Why is gathering information about infected people important?
