What questions do Epidemiologists ask?

When a disease outbreak is identified, an epidemiologist may ask some of the following questions:

• Why are infection rates of this disease higher than normal?
• Why are infection rates of this disease higher than normal in this location?
• What is the potential for the disease to spread?

What are the 3 main elements of descriptive epidemiology?

Descriptive epidemiology covers time, place, and person. Compiling and analyzing data by time, place, and person is desirable for several reasons.

What are the four methods of epidemiology?

Observational cohort. Observational case-control. Observational cross-sectional. Not an analytical or epidemiologic study.

What are the key aspects of epidemiology?

Major areas of epidemiological study include disease causation, transmission, outbreak investigation, disease surveillance, environmental epidemiology, forensic epidemiology, occupational epidemiology, screening, biomonitoring, and comparisons of treatment effects such as in clinical trials.

Is an epidemiologist a doctor?

Are epidemiologists considered medical doctors? No. While epidemiologists study and investigate the causes and sources of diseases in much the same way as medical doctors, they're not considered actual physicians. Perhaps the biggest reason why is treatment.

What does an epidemiologist?

Epidemiologists are public health professionals who investigate patterns and causes of disease and injury in humans. They seek to reduce the risk and occurrence of negative health outcomes through research, community education and health policy.

What are the 5 W's of epidemiology?

The difference is that epidemiologists tend to use synonyms for the 5 W's: diagnosis or health event (what), person (who), place (where), time (when), and causes, risk factors, and modes of transmission (why/how).

What are the three types of epidemiological studies?

Introduction

• Observational Studies. Case-Control Studies. ...
• Cohort Studies. Cohort studies initially classify patients into two groups based on their exposure status. ...
• Experimental Studies. Randomized Clinical Trials.

How does an epidemiologist describe the burden of disease?

Disease burden is the impact of a health problem as measured by financial cost, mortality, morbidity, or other indicators. It is often quantified in terms of quality-adjusted life years (QALYs) or disability-adjusted life years (DALYs).

Which is the most powerful epidemiological study?

Randomized, controlled clinical trials are the most powerful designs possible in medical research, but they are often expensive and time-consuming. Well-designed observational studies can provide useful insights on disease causation, even though they do not constitute proof of causes.

What is an example of epidemiology?

Epidemiological studies measure the risk of illness or death in an exposed population compared to that risk in an identical, unexposed population (for example, a population the same age, sex, race and social status as the exposed population).

What are the branches of epidemiology?

• Cancer Epidemiology.
• Cardiovascular Epidemiology.
• Clinical Epidemiology.
• Environmental and Occupational Epidemiology.
• Epidemiologic Methods.
• Epidemiology of Aging.
• Genetic Epidemiology and Statistical Genetics.
• Infectious Disease Epidemiology.
