Another aspect is to study the ‘vector’ or host which carries the virus and transmits . At the next level, they study the population at risk from a new pathogen.
Why are epidemiologists important?
With their research and studies, they aim to reduce risks of public health and work for the prevention of these diseases. From Hippocrates who was the first epidemiologist and found words like ‘epidemic’ and ‘endemic’ to Louis Pasteur who carried out groundbreaking research work on Rabies, epidemiologists have become vital for public health safety. ...
What are the medical mysteries of epidemiology?
The individuals solving medical mysteries, epidemiologists are the people who stand at the forefront of public health safety. With an academic background in subjects like biology, mathematics, medicine and statistics they aim to find the cause of the disease outbreak and the ways to prohibit the spreading of the disease. They try to relate the medical condition with different causes such as human behavior, environmental agents like toxins and spores genetic triggers and geographical constraints.

What is an epidemiologist?
Conversely, in experimental studies, the epidemiologist is the one in control of all of the factors entering a certain case study. Epidemiological studies are aimed, where possible, at revealing unbiased relationships between exposures such as alcohol or smoking, biological agents, stress, or chemicals to mortality or morbidity. The identification of causal relationships between these exposures and outcomes is an important aspect of epidemiology. Modern epidemiologists use informatics as a tool.
How does epidemiology help in public health?
Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results (including peer review and occasional systematic review ).

What is the difference between experimental and observational epidemiology?
In observational studies, nature is allowed to "take its course," as epidemiologists observe from the sidelines. Conversely, in experimental studies, the epidemiologist is the one in control of all of the factors entering a certain case study. Epidemiological studies are aimed, where possible, at revealing unbiased relationships between exposures such as alcohol or smoking, biological agents, stress, or chemicals to mortality or morbidity. The identification of causal relationships between these exposures and outcomes is an important aspect of epidemiology. Modern epidemiologists use informatics as a tool.
What are the three types of experimental epidemiology?
Experimental epidemiology contains three case types: randomized controlled trials (often used for new medicine or drug testing), field trials (conducted on those at a high risk of contracting a disease), and community trials (research on social originating diseases).
How to assess validity of epidemiology?
One way to assess the validity of findings is the ratio of false-positives (claimed effects that are not correct) to false-negatives (studies which fail to support a true effect). To take the field of genetic epidemiology, candidate-gene studies produced over 100 false-positive findings for each false-negative. By contrast genome-wide association appear close to the reverse, with only one false positive for every 100 or more false-negatives. This ratio has improved over time in genetic epidemiology as the field has adopted stringent criteria. By contrast, other epidemiological fields have not required such rigorous reporting and are much less reliable as a result.
