What doctor deals with factors determining the frequency of health-related conditions?

Epidemiologists also study the interaction of diseases in a population, a condition known as a syndemic. The term epidemiology is now widely applied to cover the description and causation of not only epidemic, infectious disease, but of disease in general, including related conditions.

What is study of disease called?

Pathology is the study of disease. It is the bridge between science and medicine. It underpins every aspect of patient care, from diagnostic testing and treatment advice to using cutting-edge genetic technologies and preventing disease. Doctors and scientists working in pathology are experts in illness and disease.

What is the study of disease and the changes they cause?

Pathology is the study of the causes and effects of disease or injury. The word pathology also refers to the study of disease in general, incorporating a wide range of biology research fields and medical practices.

What is the study of body’s resistance to infectious diseases?

Immunology, the scientific study of the body’s resistance to invasion by other organisms (i.e., immunity). In a medical sense, immunology deals with the body’s system of defense against disease-causing microorganisms and with disorders in that system’s functioning.

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 is the study of how disease occurs?

Epidemiology is the study of how often diseases occur in different groups of people and why. Epidemiological information is used to plan and evaluate strategies to prevent illness and as a guide to the management of patients in whom disease has already developed.

What do you call the resistance to infection?

Resistance is defined as the ability to limit pathogen burden while tolerance is defined as the ability to limit the health impact caused by a given pathogen burden. The sum of these two mechanisms defines a host’s defensive capacity.

What is the resistance to disease called?

Immunity means com- plete resistance to disease; immune means not subject to attack by a path- ogenic organism or virus.

What are the four methods of epidemiology?

Epidemiological investigations can be grouped into four broad categories: Observational epidemiology, experimental epidemiology, natural experiments, and Theoretical epidemiology. Several types study designs and measures of relationship are used in these investigations.

What are two types of disease?

Diseases can be grouped into two types:

• communicable , which are caused by pathogens and can be transferred from one person to another, or from one organism to another – in humans these include measles, food poisoning and malaria.
• non-communicable , which are not transferred between people or other organisms.

What does frequency mean in terms of Epidemiology?

Frequency refers not only to the number of health events such as the number of cases of meningitis or diabetes in a population, but also to the relationship of that number to the size of the population. The resulting rate allows epidemiologists to compare disease occurrence across different populations.

How are determinants and causes used in epidemiology?

Epidemiology is also used to search for determinants, which are the causes and other factors that influence the occurrence of disease and other health-related events. Epidemiologists assume that illness does not occur randomly in a population, but happens only when the right accumulation of risk factors or determinants exists in an individual.

How are rates and patterns related in epidemiology?

The resulting rate allows epidemiologists to compare disease occurrence across different populations. Pattern refers to the occurrence of health-related events by time, place, and person.

How are epidemiologists used to search for risk factors?

Epidemiologists assume that illness does not occur randomly in a population, but happens only when the right accumulation of risk factors or determinants exists in an individual. To search for these determinants, epidemiologists use analytic epidemiology or epidemiologic studies to provide the “Why” and “How” of such events.
